Abstract (sommario):

AbstractThis paper proposes moving horizon estimation (MHE) to estimate the state variables of autonomous vehicle linear systems under measurement noises. To solve the MHE optimization problem, quadratic programming is employed. The steering angle, yaw angle, and global position constraints of an autonomous vehicle are considered in the estimation design. According to the simulation results, it can be observed that although the longer MHE step can give better results compared to the shorter MHE step, the difference in the MHE step only slightly affects the estimated results. However, the longer MHE step can increase the computational time. Additionally, the proposed MHE scheme is compared to the Kalman filter (KF) estimator. Based on the obtained results, the KF gives a better estimation than the MHE, but this notion must be verified for other case studies.Keywords: autonomous vehicle; Kalman filter; linear system; MHE; quadratic programming. AbstrakPaper ini mengusulkan moving horizon estimation (MHE) untuk mengestimasi variabel keadaan sistem linier kendaraan otonom karena pengaruh noise pengukuran. Untuk menyelesaikan masalah optimasi MHE, digunakan pemrograman kuadratik. Kendala sudut kemudi, sudut yaw dan posisi global dari kendaraan otonom dipertimbangkan dalam desain estimasi. Dari hasil simulasi dapat diketahui bahwa meskipun langkah MHE yang lebih panjang dapat memberikan hasil yang lebih baik dibandingkan dengan langkah MHE yang lebih pendek, perbedaan langkah MHE hanya sedikit mempengaruhi hasil estimasi. Namun, langkah MHE yang semakin panjang dapat meningkatkan waktu komputasi. Selain itu, skema MHE yang diusulkan dibandingkan dengan estimator Kalman filter (KF). Berdasarkan hasil yang diperoleh, KF memberikan estimasi yang lebih baik daripada MHE, tetapi gagasan ini harus diverifikasi untuk studi kasus lainnya.Kata Kunci: kendaraan otonom; Kalman filter; sistem linier; MHE; pemrograman kuadratik. 2020MSC: 62P35, 65D19

Abstract (sommario):

Intestinal epithelial barrier function is closely associated with the development of many intestinal diseases. Heat-killed Lacticaseibacillus paracasei (HK-LP) has been shown to improve intestinal health and enhance immunity. However, the function of HK-LP in the intestinal barrier is still unclear. This study characterized the inflammatory effects of seven HK-LP (1 μg/mL) on the intestinal barrier using lipopolysaccharide (LPS) (100 μg/mL)-induced Caco-2 cells. In this study, HK-LP 6105, 6115, and 6235 were selected, and their effects on the modulation of inflammatory factors and tight junction protein expression (claudin-1, zona occludens-1, and occludin) were compared. The effect of different cultivation times (18 and 48 h) was investigated in response to LPS-induced intestinal epithelial barrier dysfunction. Our results showed that HK-LP 6105, 6115, and 6235 improved LPS-induced intestinal barrier permeability reduction and transepithelial resistance. Furthermore, HK-LP 6105, 6115, and 6235 inhibited the pro-inflammatory factors (TNF-α, IL-1β, IL-6) and increased the expression of the anti-inflammatory factors (IL-4, IL-10, and TGF-β). HK-LP 6105, 6115, and 6235 ameliorated the inflammatory response. It inhibited the nuclear factor kappa B (NF-κB) signaling pathway-mediated myosin light chain (MLC)/MLC kinase signaling pathway by downregulating the Toll-like receptor 4 (TLR4)/NF-κB pathway. Thus, the results suggest that HK-LP 6150, 6115, and 6235 may improve intestinal health by regulating inflammation and TJ proteins. Postbiotics produced by these strains exhibit anti-inflammatory properties that can protect the intestinal barrier.

Abstract (sommario):

A low-power, monochromatic, tunable diode laser is used to selectively populate the cesium 62P3/2 (Fe = 2, 3, 4, 5) hyperfine-structure levels in a pure optically thick vapour in the presence of a dissipative surface. The integrated retrofluorescence intensities for the 852 nm (62P3/2 → 62S1/2), 894 nm (62P1/2 → 62S1/2)> and 455 nm (72P3/2 → 62S1/2) lines have been measured and analyzed. When the laser frequency is scanned through the [62S1/2(Fg) → 62P3/2(Fe)] hyperfine resonance line, the sensitized retrofluorescence spectral signal corresponding to the 894 nm line has a profile significantly different from the retrofluorescence signal at the 852 nm line, but rather similar to the profiles of the lines associated with the energy-pooling collisions. The population of the 62P1/2 atomic level in an optically thick vapour cannot be explained only by the fine-structure excitation transfer process [Cs (62P3/2) + Cs (62S1/2) ↔ Cs (62P1/2) + Cs (62S1/2)] usually accepted in an optically thin vapour. We have investigated inelastic collisions in the populating mechanisms of 62P1/2 level starting from the 62P3/2 level exited by the monochromatic laser taking into account the presence of an electrically conductive surface. It appears from our experimental and theoretical investigations that, the spectral properties of the laser-induced Cs 894 nm sensitized retrofluorescence in a pure optically thick vapour near a dissipative surface cannot be explained by both the conventional mechanism and cascade collisions. The satisfactory interpretation of the experimental results is an open problem of atomic spectroscopy.PACS Nos.: 32.30, 32.50, 32.70, 32.80, 34.10, 34.50, 42.62

Abstract (sommario):

Une très faible lumière nous parvient depuis le ciel. Celle-ci n'est pas uniformément répartie sur la carte du ciel mais présente des anistropies. En analysant ces anistropies, nous pouvons déduire son spectre de puissance, ce qui nous permet de déduire les paramètres de l'univers. En supposant que le modèle statistique de génération de ces anistropies soit un modèle hiéarchique linéaire Gaussien et en ajoutant une distribution a priori sur les paramètres, nous pouvons faire de l'inférence Bayésienne sur ces paramètres. Ceci nous permet d'avoir non pas seulement un estimateur ponctuel des paramètres mais aussi des barres d'erreur sur ces quantités. Afin de mener à bien cette inférence, nous reprenons et développons l'échantillonneur de Gibbs utilisé jusque là dans la littérature sur l'analyse du fond diffus cosmologique. Nous proposons un moyen de raccourcir le temps de résolution d'un système en très grande dimension tout en gardant la distribution cible invariante. Nous proposons également un algorithme basé sur une variable auxiliaire pour contourner cette résolution. Finalement, en présentant les paramétrisations centrée et non centrée, nous utilisons une stratégie d'interweaving afin d'avoir un algorithme mélangeant bien sur l'ensemble du ratio signal sur bruit.Le second projet concerne la compression des chaînes de MCMC. Sous-échantillonner une chaîne de Markov augmente toujours la variance asymptotique de l'estimateur obtenu. Nous voulons donc garder les points les plus représentatifs afin que cette variance asymptotique n'augmente pas trop. En utilisant une méthode d'échantillonnage pour des sondages et des "control variates", nous proposons une méthode en deux étapes afin de ne garder les points les plus représentatifs de la loi cible parmi une chaîne de MCMC: d'abord, nous utilisons des control-variates afin d'obtenir un estimateur s'écrivant comme une somme pondérée de la chaîne initiale. Ensuite, nous utilisons la méthode du cube afin de sous-échantillonner la chaîne pondérée obtenue à l'étape précédente. Nous proposons une façon de gérer les poids négatifs que la première étape peut donner. Nous proposons également deux façons d'avoir des control-variates: l'une, basée sur le "Stein trick" et la seconde, basée sur les control-variates de Gibbs. Ainsi, notre méthode ne nécessite pas la fonction de score
We receive a faint light from the sky. This light is not uniform on the map of the sky but presents anisotropies. From these anisotropies, we can deduce its power spectrum, which in turn allows us to determine the cosmological parameters of the universe. Assuming the statistical model generating the sky map is a hierarchical linear Gaussian model and adding a prior distribution on the parameters, we can make Bayesian inference on these parameters. This allows us not only to have point estimates of the parameters, but also error bars on these quantities. In order to make this inference, we further develop the usual Gibbs sampler used in the CMB data analysis literature. We propose a way to shorten the resolution of a very high dimensional system while keeping the target distribution invariant. We also offer an algorithm based on an auxiliary variable to get around this resolution. Finally, using the concepts of centered and non centered parametrization, we use an interweaving strategy to have good mixing properties on the entire signal-to-noise ratio range.The second project regards the compression of MCMC chains. Subsampling a Markov chain always increases the asymptotic variance of the resulting estimator. Hence we want to keep the points that are the most representative so that this variance does not increase too much. Using a survey sampling method and control variates, we propose a two steps procedure to keep the points that are the most representative of the target distribution out of a MCMC chain: first, we use control-variates in order to get an estimator which writes as a weighted sum of the chain. Then, we use the cube method to subsample the weighted chain we got at the end of the first step. We propose a way to deal with negative weights arising at the first step, which are incompatible with the cube method. We also provide two ways to build control-variates: one based on the Stein trick and the other one based on the Gibbs control variates. Hence, our method does not necessitate the availability of the score function

Abstract (sommario):

This thesis examines David Hartley’s Observations on Man (1749) and elucidates how Hartley’s mechanical approach to mind, his conception of emotion, and the religious status he awards the body were newly relevant after 1791. In this way it identifies a ‘Hartlean culture’ within the Romantic period and seeks to explore how such an intellectual climate influenced the radical writers William Blake (1757–1827) and Mary Wollstonecraft (1759–1797). Blake and Wollstonecraft were acquainted with the famous bookseller Joseph Johnson, who republished Observations on Man in various forms and versions between 1775 and 1801. They also had an association with Johnson’s circle; the Hartlean concepts found throughout their work evidence Hartley’s latent popularity within intellectual culture, as well as the writers’ engagement with contemporary philosophical ideas. I propose that the renewed curiosity in Hartley during the 1790s reveals a specific religious and revolutionary culture wherein non-conformist views about Christianity and new ideas about the body, emotion and women flourished. Such a cultural moment renders Hartley a particularly important figure for debate since he integrated progressive values about equality and faith alongside advancing understanding of anatomy and mind. Hartley identified how God and happiness could be found physically within each person. He did this by combining a complex theory of vibrations and theory of association, where the body and mind functioned mechanically through a person’s feelings of pleasure and pain. These feelings manifested as physical vibrations and eventually led every person to desire goodness until finally, they can become ‘Godlike’ themselves. Hartley’s amalgamation of Christian and new theoretical concepts appealed to Blake and Wollstonecraft, and was much unlike the approach of Joseph Priestley who abridged Observations in 1775 to promote a wholly ‘scientific’ text. In this way, we can see resonances between Hartley, Blake and Wollstonecraft, even if they existed in different cultural contexts. In rethinking Blake and Wollstonecraft through Hartley, I offer new insights into their feminism. In particular I attend to how Hartlean culture enabled these writers to re-imagine gender and emotion: Wollstonecraft reinstates the female experience back into Hartlean concepts in order to promote women’s emotional potential and what she understands as the special power of the female-female bond. Blake responds to both Wollstonecraft and Hartley with his elevation of the feminine, one that envisions new potential for both sexes, emotionally and spiritually. In both cases, the writers share a fascination for the image of the female saviour, and they use terminology and concepts found in Hartley’s work to communicate their views. In being attentive to the shared vocabulary and ideas of these three writers’ works, this thesis highlights the importance of David Hartley and Hartlean culture for the field of Romantic Studies. It also illuminates Observations on Man as a vital contribution to the intellectual context of the 1790s.

Abstract (sommario):

Most common building materials are polymer based. Thus toxic products evolving from burning polymers is the single most important factor in fire fatalities. Fire hazard calculations require modelling of heat generation, toxic combustion products generation and its transport in realistic building scenarios involving common building material. However, the thermal decomposition, combustion behaviour and chemical kinetics for common polymers like wood, plastics, rubber and textiles are extremely complex. In the present study, a methodology (STEM-LER: the Scalar Transport Equation based Model using the Local Equivalence Ratio concept) based on solving separate transport equations for the species and using the yield correlations obtained from bench-scale experiments to model the source terms is proposed to predict the products generation and its transport during enclosure fires. Modelling of complex solid phase degradation and chemical kinetics of polymers is bypassed by measuring the product yields as a function of equivalence ratio by burning the samples in a bench-scale combustion apparatus called Purser furnace. Since the accuracy of prediction depends upon the quality of the yield data obtained from the Purser furnace, attempts were also made to numerically investigate this bench-scale toxicity test method in order to understand its modus operandi. Finally, a preliminary assessment on the effect of cable fires on building evacuation for the simulated fire scenarios was carried out using a sophisticated evacuation model.

Abstract (sommario):

The central concern of this thesis is the study of critical behaviour in models of statistical physics in the upper-critical dimension. We study a generalized n-component lattice |φ|⁴ model and a model of weakly self-avoiding walk with nearest-neighbour contact self-attraction on the Euclidean lattice ℤd. By utilizing a supersymmetric integral representation involving boson and fermion fields, the two models are studied in a unified manner. Our main result, which is contingent on a small coupling hypothesis, identifies the precise leading-order asymptotics of the two-point function, susceptibility, and finite-order correlation length of both models in d = 4. In particular, we show that the critical two-point function satisfies mean-field scaling whereas the near-critical susceptibility and finite-order correlation length exhibit logarithmic corrections to mean-field behaviour. The proof employs a renormalization group method of Bauerschmidt, Brydges, and Slade based on a finite-range covariance decomposition and requires two extensions to this method. The first extension, which is required for the computation of the finite-order correlation length (even for the ordinary weakly self-avoiding walk and |φ|⁴ model), is an improvement of the norms used to control the evolution of the renormalization group. This allows us to obtain improved error estimates in the massive regime of the renormalization group flow. The second extension involves the identification of critical parameters for models initialized with a non-zero error coordinate coupled to a marginal/relevant coordinate. This allows us, for example, to realize the two-point function and susceptibility for the walk with self-attraction as a small perturbation of the corresponding quantities without self-attraction, whose asymptotic behaviour was determined by Bauerschmidt, Brydges, and Slade. This establishes a form of universality.

Abstract (sommario):

Viral myocarditis is an inflammatory heart disease caused by viral infection, which is a major cause of sudden death in children and young adults. Among the various viruses, coxsackievirus B3 (CVB3) is a predominant pathogen of viral myocarditis. As CVB3 replication is tightly tangled with signaling pathways in host cells, an in-depth study of CVB3-host interactions would promote the understanding of the pathogenesis of viral myocarditis and provide critical drug targets for the development of therapeutics. CVB3 infection induces different types of stress in host cells, and in turn, the cells respond to the stress via expressing certain stress-responsive proteins (SRPs) to counteract the stress for cell survival. During the co-evolution of virus and host, CVB3 has developed sophisticated strategies to modulate and utilize SRPs to benefit its own replication. The main objective of this dissertation is to investigate the modulation and functional roles of SRPs in CVB3 infection and CVB3-induced myocardium damage. I hypothesize that 1) CVB3 infection differentially regulates the expression and activity of SRPs at transcription, translation or post-translation level; 2) the dysregulation of SRPs benefits CVB3 replication and promotes CVB3-induced cell damage. This dissertation mainly focuses on two SRPs, the inducible heat shock 70 kDa protein (Hsp70) and nuclear factor of activated T-cell 5 (NFAT5), during CVB3 infection. Using in vitro (cell culture) and in vivo (mouse) models, I demonstrated an increase of Hsp70 but a decrease of NFAT5 during CVB3 infection. Further studies elucidated the mechanism underlying such changes as well as the feedback effects on CVB3 replication. Hsp70 was upregulated via CaMKII-HSF1 signaling cascade activated in CVB3 infection and in turn promoted CVB3 infectivity via stabilizing viral genome and benefiting viral translation. NFAT5 was cleaved by CVB3 proteases 2A and 3C, generating a 70 kDa dominant negative truncate, which inhibited the iNOS-mediated anti-viral activity of NFAT5. Together, my findings have uncovered the new roles of SRPs in CVB3 infection and potential novel drug targets for CVB3-induced myocarditis.

Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Chemical Engineering, 2011.
Cataloged from PDF version of thesis.
Includes bibliographical references.
Electroresponsive layer-by-layer (LbL) polymer films and polymer nanocomposite films were investigated as model systems for electrically triggered drug delivery applications and "mechanomutable" surface coating applications. Two strategies were implemented in the design of these electroresponsive films: the use of redox-active, chargeshifting nanoparticles and the control over local pH utilizing the electrochemical reduction of dissolved oxygen. These strategies and the multiple materials systems explored are described below. Redox-active Prussian Blue (PB) nanoparticles exhibit multiple, stable oxidation states and can shift their charge in response to mild electric potentials. The inherently negatively charged particles may be self-assembled into LbL films along with positively charged polyelectrolytes. When the PB in an LbL film is oxidized to its neutral state, dissolution of the film occurs as cohesive ionic crosslinks are broken and excess charge in the film brings in ions and water for electroneutrality, which solubilize the film components. The release of the polyanion dextran sulfate and the small molecule antibiotic gentamicin sulfate were precisely controlled with an electric potential. When PB is reduced, the negative charge on the particle is doubled, which results in film swelling and a decrease in stiffness. In films comprising PB and linear polyethyleneimine, reversible thickness changes on the order of 5-10% and reversible elastic modulus changes on the order of 50% (between 3.40 GPa and 1.75 GPa) were observed. Employing the second strategy mentioned above, the local pH near an electrode surface may be increased to more basic values when dissolved oxygen is electrochemically reduced to hydroxide ions. In the first model system explored, hydrogen bonded (H-bonded) films comprising polyvinylpyrrolidone (PVPON) and tannic acid (TA), were dissolved at constant bulk pH by applying mild potentials (-0.25 V to -1.00 V vs. Ag/AgCl). The dissolution mechanism and kinetics could be tuned with the magnitude of the applied voltage and the concentration of dissolved oxygen. In the second model system explored, films comprising polyallylamine hydrochloride (PAH) and sulfonated polystyrene (SPS) were found to undergo reversible and dramatic swelling/deswelling transitions on the order of roughly 300 vol% and mechanical transitions on the order of 600-800% (shear modulus between 230 kPa and 1.9 MPa and loss modulus between 90 kPa and 620 kPa). This thesis contributes to the applied materials science branch of chemical engineering. New polymer and polymer nanocomposite thin films were developed that can be further engineered and incorporated into implantable drug delivery devices for electrically triggered drug delivery or incorporated into MEMS and microfluidic systems for flow control or biomedical applications. Furthermore, the model systems presented here open doors for fundamental work on the transport of electrons, ions, and water through these electroresponsive films and the implications of transport phenomena on the control over film dissolution and swelling responses.

Abstract (sommario):

We report microfabricated tunable capacitors based on plastically deformed vertical comb sets using a batch process. The arrangement of cascaded comb finger sets and the uniqueness of the angular vertical comb actuators enable large tuning ratio with a small angular displacement. The capacitors are made of 50μm-thick single-crystal silicon on SOI wafer and actuated by self-aligned vertical comb-sets giving a tuning ratio of 4.93 from 0.194 to 0.96pF with a tuning voltage of 100 Volts. As such, this tunable capacitor could find applications in RF communication such as parametric amplifiers, harmonic frequency generators and voltage-controlled oscillators.

Abstract (sommario):

Based upon the commonly used Sapareto-Dewey thermal dose formula, a thermal treatment is divided into four periods: 1) period-1 is from 37°C to 43°C, 2) period-2 is from 43°C to Tpeak, 3) period-3 is from Tpeak to 43°C, and 4) period-4 is 43°C to 38°C. A recent study derived a closed form thermal dose formula based on a combined term, the “effective cooling frequency,” revealed that one can determine the best performance of a thermal therapy by concentrating on the cooling periods: period-3 and period-4. As an extension, this study used a closed-form temperature solution to investigate the influences from both cooling terms (perfusion and thermal conduction) separately. The results determined the upper bound of the peak temperature for pulses with different focal sizes under different blood perfusion values. Under practical settings, no pulse should introduce peak temperature higher than 67°C to avoid overdosing when the desired thermal dose is 240CEM43°C. It also showed that pulses with focal size smaller than or equal to 4 mm benefit the perfusion independence for the following quantities: the upper bound on the peak temperature, the treatment size, and the time/temperature for which 90% thermal dose is accumulated. Thus the conduction dominates the cooling process for each single pulse heated by the highly focused SFUS applicators when the pulses are properly isolated temporally. Results from this study further provide an estimation of the closest distance between two pulses and the time/temperature to re-activate the consecutive pulses. Thus the results can guide the researchers to design more efficient treatment protocol for multiple-pulse thermal therapies.

Abstract (sommario):

By Three Dimensional X-ray Diffraction (3DXRD) microscopy it is possible to characterize microstructures non-destructively in 3 dimensions. The measurements are furthermore typically so fast that dynamics may be monitored in-situ, giving also the 4th dimension, namely the time. The 3DXRD technique is based on diffraction of high energy x-rays from third generation synchrotron sources. In the present paper the 3DXRD technique is described and it’s potentials are illustrated by examples relating to elastic and plastic strains, recovery, recrystallization and grain growth.

Abstract (sommario):

Turbojet engines power most of the large military and commercial aircraft in production today. These types of engines are chosen over conventional piston-driven engines because of the turbojet’s superior fuel economy and thrust. To understand how turbojet engines can be compared and optimized, it is necessary to fully characterize their performance. This is generally achieved by calculating thermodynamic efficiency values for each component in the engine, and for the engine as a whole. For this research project, the Turbine Technologies SR-30 centrifugal flow turbojet engine was investigated. An adjustable coupling was designed to permit a single-point thermocouple to be moved and secured within the engine. From the data taken at multiple locations and throttle settings, temperature profiles of the compression and combustion chambers were created. A thermal/fluid dynamic equation routine was developed using Engineering Equation Solver (EES), in order to propagate these temperature profiles through efficiency and thrust calculations. The temperature profiles did not significantly affect theoretical thrust values. However, the dependence of component efficiency values on spatial temperature variation within the engine was significant. In the compression chamber, it was found that a 30°C variation in the temperature across the chamber resulted in a 15% variation in the calculated compressor efficiency. In the inner region of the combustion chamber, a variation in 20°C yielded a 20% variation in calculated turbine efficiency. In the outer region of the combustion chamber, where the temperature varied by almost 400 degrees Celsius, the turbine efficiency varied by about 600%. This work suggests optimal placement of the compression and combustion stage thermocouples when the SR-30 turbojet is to be used for undergraduate laboratories. It also highlights the risks posed by relying on single-point measurements to characterize complex flows.

Abstract (sommario):

In this paper, single phase incompressible liquid flow in a new microchannel heat sink design, which includes flow bifurcation, is studied experimentally and numerically. The experimental setup and device fabrication are briefly explained. The experimental results are presented with uncertainty in the measurements. The numerical model is based on a commercial code and is validated by experimental results with the same initial and boundary conditions. Numerical results with both constant fluid properties and variable properties are compared with the experimental data. The thermal-hydraulic performance of the new design is investigated. The effects of the resulting fluid flow and the geometry on the thermal resistance of the system are discussed.

Abstract (sommario):

The aim of this work is the reduction of the steady state amplitude of harmonically forced simply supported beams using mass dampers. The considered system consists of a mass damper attached to a simply supported beam with a harmonic force applied at a given point along its span. Traditionally, passive vibration devices such as mass spring dampers or mass dampers were attached to beams and carefully designed to minimize the maximum amplitude at a given point along their span. Since minimizing the amplitude at one point of the beam might increase it at another point, in this work the maximum amplitude along the entire beam span is minimized. The problem is solved first using an approximate method. For a given mass ratio, the optimal location of the mass damper is determined first, and then the optimal damping constant is calculated. Fixed-lines of the amplitude of the entire span of the beam which are independent of the damping constant are determined. The optimal placement of the mass damper is chosen such that the maximum of these lines is minimized. Then, the optimal damping constant is obtained analytically from an average of two damping ratios corresponding each to one of the peaks of the amplitude of the entire beam span to coincide with one of the two equally leveled maxima of the fixed-lines. The optimal placement and damping constant are calculated for all possible positions of the point force on the beam. These results are compared to those obtained from an exact numerical optimization procedure. The results are written in dimensionless form and can be applied to a system with any material and geometric properties.

Abstract (sommario):

The purpose of this study is to observe methane jet flames under varying levels of nitrogen dilution and coflowing air. The jet flames were examined in order to determine the conditions for which liftoff and blowout occur under conditions that strain the flame. Methane flow rates were varied, corresponding to intermediate lifted positions to blowout. A sequence of images were taken at each level of dilution and coflow, and were used to determine the lowest radial and axial position of the flammability limit. These flammability regions were compared to the lean flammability limit. It was observed that flame shape and liftoff were considerably more influenced by the effects of the coflowing air compared to the presence of the diluents, and that flames under coflow lost the trailing diffusion flame earlier, which has been shown to be a marker for flame blowout.

Abstract (sommario):

Droplet impingement is a fundamental process for many applications particularly those involving heat transfer. While there has been considerable work over many years on understanding the flow and heat transfer processes, we have only recently been able to fabricate controllable nanostructured surfaces. Surface structure can have a massive impact on the droplet impact process dynamics and the associated convective heat transfer from the liquid droplet to the surface. In this paper we examine the impact dynamics and heat transfer using simultaneous high speed thermal imaging of the liquid from below, and high speed video camera images from the side for different surfaces, ranging from hydrophilic to superhydrophobic. In this way we characterize the heat transfer process as a function of the droplet dynamics and the surface properties. We show that the heat transfer rate is primarily affected by the contact line dynamics and the wetted area. Due to the superhydrophobic roughness scale being relatively small, the interface resistance offered by the trapped air has only a small effect on the heat transfer rate, and only in the inertia dominated region before maximum spreading diameter. Finally we show that the overall cooling effectiveness of as single impinging droplet is very dependent on the surface properties with hydrophilic surfaces offering the highest cooling effectiveness.

Abstract (sommario):

The problem of water-in-oil emulsion destruction is related to many technological processes in the oil-and-gas industry, especially in extracting and processing of oil, preparation and transportation of oil, and liquidation/recycling of oil-sludge barns. High stability of water-in-oil emulsions is principally conditioned by the presence in oils of heavy high-molecular polar components that envelope water droplets and prevent coalescence of these droplets. Using conventional techniques to destroy the emulsions yields no positive results. Employing electromagnetic field energy is one of the ways to address this problem. The paper presents the results of an experimental study of the water-in-oil emulsion destruction in radio-frequency and microwave electromagnetic fields. A mathematical model is also proposed to describe the process of electromagnetic impact on water-in-oil emulsions.
