Abstract:
Several features of heat transfer on enclosing surfaces are discussed including temperature distributions in a room heated by a floor heater. Numerical analyses on radiative and convective heat transfer were carried out against several partial floor heating. Partial floor heating produces different types of temperature distribution between the heated and non-heated places, which is a remarkable characteristics found out in this study. In the heated places, the temperature distribution is almost the same as that of typical floor heating. However, in the non-heated places, air temperature differs by 6 °C (3.6 °Difference) between a point near the floor surface and a point well above that. Heating efficiency of partial heating slightly depends on the set place as well as its Area. Moreover, convective heat exchange constitutes approximately half of the total heat exchange

Abstract:
In this study, plate-fin heat sinks with partial heating under forced convection were experimentally investigated. The base temperature profiles of the plate-fin heat sinks were measured for various heating lengths, heating positions, flow rates, and channel widths. From the experimental data, the effects of heating length, heating position, and flow rate on the base temperature profile and the thermal performance were investigated. Finally, the characteristics of the optimal heating position were investigated. As a result, it was shown that the optimal heating position was on the upstream side in the case of the heat sinks under laminar developing flow, as opposed to the heat sinks under turbulent flow. It was also shown that the optimal heating position could change significantly due to heat losses through the front and back of the heat sink, while the effects of the heat loss through the sides of the heat sink on the optimal heating position were negligible. In addition, it was shown that the one-dimensional numerical model with empirical coefficients could predict the important trends in the measured temperature profiles, thermal resistances, and optimal heating lengths.

Abstract:
AbstractThermal deformations in symmetric and antisymmetric cross-ply laminated beams subjected to partial heating are investigated. Some regions of the beam are subjected to thermal loads and the others are thermally unloaded (ΔT = 0). The thermal field is expressed in terms of Heaviside discontinuity functions. The state space approach along with Jordan canonical form is used to generate exact solutions for the thermoelastic response of beams for arbitrary boundary conditions. A first order shear deformation theory is used in the analysis. Deflections are computed for beams subjected to partial heating with various lamination schemes and boundary conditions undergoing uniform and linearly varying temperature through the thickness. Exact thermal deflection curves are presented for beams under step-wise varying temperature field. The solutions presented in this study can readily be used to investigate the thermoelastic behavior of narrow chip-substrate structure, laminated member in laser cutting, composite link in hypersonic vehicle, and etc.

Abstract:
To improve recycling quality, it is necessary to develop a demolition technology that can be combined with existing crushing methods that employ large shredding-efficient equipment. The efficient collection of bones in a segmentation dismantling method must be considered according to the procedure. Furthermore, there is a need for the development of partial dismantling technologies that enable efficient remodeling, maintenance, and reinforcement. In this study, we experimentally investigated the temperature-rise characteristics of reinforced concrete through partial rapid heating during high-frequency induced heating. Accordingly, the chemical and physical vulnerability characteristics of the reinforced concrete were verified by studying the thermal conduction on the surface of the rebars and the cracks caused by the thermal expansion pressure of the rebars. Furthermore, we aimed to verify the applicability of the proposed technology by specifying the vulnerability range of the reinforced concrete based on the heating range, as well as the appropriate energy consumption. We investigated the temperature rise and temperature distribution characteristics of the rebar surfaces based on diameter, length, bar placement conditions, heating distance, heating coil location, and output, using reinforced steel of grade SD345. Maximum powers of 5, 6, and 10 kW, and inductive heating were used to achieve satisfactory results.

Neste trabalho estamos interessados em estudar, mediante simulações computacionais, se o aquecimento eletromagnético é capaz de melhorar o deslocamento do óleo pela água. Nesta direção, nos baseamos nos resultados obtidos pela equipe da TU Delft da Holanda, que desenvolveu experimentos de laboratório que demonstravam a distribuição da temperatura em um meio poroso, onde o óleo está sendo deslocado pela injeção de água, gerada por aquecimento eletromagnético. Para tanto, definimos o modelo matemático que governa o problema em questão regido por equações diferenciais parciais das leis de conservação de massa e energia. Assim, partindo da caracterização do contínuo e estendendo a lei de Darcy para o caso multifásico, através da introdução do conceito de permeabilidades relativas dos fluidos, derivamos um sistema acoplado de equações diferenciais parciais com coeficientes variáveis e termos não lineares formulados em função da velocidade de Darcy para o escoamento bifásico (água, óleo) aquecido por ondas eletromagnéticas. O modelo matemático é discretizado utilizando o método de diferenças finitas no tempo e no espaço e a técnica Splitting. Dessa forma dividimos o sistema de equações diferencias parciais em dois subsistemas. O primeiro subsistema consiste em resolver a parte difusiva e reativa e o segundo subsistema tem por objetivo a resolução do termo convectivo. O método numérico desenvolvido é validado por simulações computacionais que visam a comparação com os resultados obtidos experimentalmente e com soluções semi-analíticas, para este problema, que foram derivadas pelo método do princípio de Duhamel. Além disso, o método proposto quando aplicado para o caso geral da simulação do escoamento bifásico com aquecimento eletromagnético demonstrou um ganho de 1.67%, se comparado ao método sem aquecimento.
In this work we are interested in studying, through computational simulations, if the electromagnetic heating is able to improve the displacement of the oil by water. In this direction, we rely on the results obtained by the TU Delft team from the Netherlands, which developed laboratory experiments that demonstrated the temperature distribution in a porous medium where the oil is being displaced by the injection of water generated by electromagnetic heating. For this, we define the mathematical model that governs the problem in question governed by partial differential equations of the laws of conservation of mass and energy. Thus, starting from the characterization of the continuum and extending Darcy’s law to the multiphase case, by introducing the concept of relative permeabilities of fluids, we derive a coupled system of partial differential equations with variable coefficients and non-linear terms formulated as a function of the velocity of Darcy for two-phase flow (water, oil) heated by electromagnetic waves. The mathematical model is discretized using the finite difference method in time and space and the Splitting technique. In this way we divide the system of partial differential equations into two subsystems. The first subsystem consists of solving the diffusive and reactive part and the second subsystem aims to solve the convective term. The numerical method developed is validated by computational simulations aimed at the comparison with the results obtained experimentally and with semi-analytical solutions, for this problem, which were derived by the Duhamel principle method. In addition, the proposed method when applied to the general case of simulation of the biphasic flow with electromagnetic heating demonstrated a gain of 1.67%, when compared to the non-heating method.

Abstract:
This thesis is composed of three articles, which have the common denominator that they are studies of heating of oxygen ions in the high altitude cusp and mantle in the terrestrial magnetosphere. All data analysis are based on observational data from the Cluster satellites. Oxygen ions originate in the ionosphere, from where they flow up along open cusp field lines. This upflowing ionospheric plasma is generally gravitationally bound and will return as ionospheric downflow. However, if the plasma is sufficiently energized it may overcome gravity and reach the magnetosphere. Further energization is able to put the plasma on trajectories leading downstream along the magnetotail, which may cause the plasma to escape into the magnetosheath. This thesis considers energization of oxygen ions through wave-particle interactions. We show that the average electric spectral densities in the altitude range of 8-15 Earth radii are able to explain the average perpendicular temperatures, using a simple gyroresonance model and 50% of the observed spectral density at the O+ gyrofrequency. We also show that the phase velocities derived from the observed low frequency electric and magnetic fields are consistent with Alfvén waves. Strong heating is sporadic and spatially limited. For three case studies of strong heating, we show that the regions of enhanced wave activity are at least one order of magnitude larger than the gyroradius of the ions, which is a condition for the gyroresonance model to be valid. An analysis indicates that enhanced perpendicular temperatures can be observed over several Earth radii after heating has ceased, suggesting that high perpendicular-to-parallel temperature ratio is not necessarily a sign of local heating. This also explains why we sometimes observe enhanced temperatures and low spectral densities. Three events of very high temperatures and simultaneously observed high spectral densities were studied, and we showed that the temperatures could be explained with the simple gyrofrequency model. We have also provided average diffusion coefficients at different altitudes, which can be used for ion heating and outflow modeling.

Abstract:
The radiant exchange problem for an isothermal spherical cavity having diffuse-specular walls is solved and the distribution of the local heat transfer for various opening angles and surface emissivities is obtained. Subsequently, the overall emission from the cavity (i. e., the apparent emissivity of the cavity) is calculated for various opening angles and surface conditions. In addition, the overall absorption characteristics of spherical cavities having purely specular walls is investigated analytically for the case of collimated radiation entering the cavity. Various opening angles and surface conditions are considered. The Monte Carlo method is utilized to support the results obtained from the analytical calculations. Results show that in spherical cavities the apparent emissivity is not very sensitive to the degree of specularity of the cavity wall. Also, there are situations in which the diffuse cavity is a more efficient emitter than a specular cavity. Absorption characteristic results show that for cavities having purely specular walls the absorption of collimated radiation is highly dependent on the angle of incidence of radiation on the opening for small opening angles.

Abstract:
A dynamical technique for the study of tokamak energy and particle transport has been developed. The plasma in the medium-sized DITE tokamak was perturbed by the application of modulated electron cyclotron resonance heating, with wave-launching from the high-field side. These experiments were carried out with absorption at various distances from the plasma centre, over a range of densities. Energy transport through the electron channel was dominant, and the variations in electron temperature and density were measured using the soft X-ray, electron cyclotron emission and microwave interferometer diagnostics. Analysis in the frequency domain enabled the propagation of the thermal wave to be followed. The observed behaviour was generally indicative of diffusive propagation of the thermal perturbation. Further observations indicated a modulation of the horizontal plasma shifts, diffusive propagation to the edge and a low modulation level of line-averaged density. In some atypical cases, the observed behaviour was qualitatively different; this type of behaviour was accompanied by a pronounced sawtooth oscillation locked with the modulation. Two models have been employed for the interpretation of these results. The first model, based on the diffusive thermal transport of the perturbation, has led to results in good agreement with the experimental data. Values of the electron thermal diffusivity were deduced, in good agreement with those obtained from the alternative techniques of power balance analysis and sawtooth heat pulse propagation analysis; such agreement has not been universally obtained in similar experiments. The width of the absorption region has emerged as an important consideration in this analysis. A more complex model, including non-linear, coupled equations of particle and energy balance, has produced results in partial agreement with the experimental data, supporting, to some extent, the presence of coupled transport. It has been demonstrated how perturbation techniques can afford a useful means of testing transport models.

Neste trabalho apresentamos um estudo analítico sobre a recuperação de óleo pesado utilizando injeção de água, que é aquecida por meio de ondas eletromagnéticas de alta freqüência. Recentemente, foi feito um experimento (descrito em [12]), onde a água foi injetada num meio poroso, aquecida por meio de ondas eletromagnéticas. Os resultados do experimento mostram que o aquecimento mediante ondas EM melhora o deslocamento do óleo pela água. Desta maneira, apresenta-se a injeção de água com aquecimento por ondas EM como um método viável na recuperação de óleo. Consideraremos um modelo matemático simples descrevendo o experimento mencionado acima, que consiste de duas leis de balanço, uma para a energia e outra para a massa da água. O objetivo do trabalho é usar o Princípio de Duhamel e a Teoria das Leis de Conservação para encontrar soluções semi-analíticas deste modelo simplificado. Segundo [8], utilizamos o Princípio para achar a solução da equação de balanço de energia do tipo Convecção-Reação-Difusão para o problema de transporte de calor num meio poroso na presença de uma fonte de ondas eletromagnéticas. A equação de balanço para a massa da água é uma equação diferencial parcial não linear de primeira ordem do tipo Buckley-Leverett (Veja [4] e [7]). Ela será resolvida usando a Teoria das Leis de Conservação. Segundo [15], a solução deste problema contém ondas de rarefação e choque.
In this work, we present the results obtained by analytical study of heavy oil recovery by water flooding and electromagnetic (EM) heating of high frequency. Recently, an experiment was made, where water was injected into a porous medium, warmed by means of electromagnetic waves. The experiment results show that EM heating improves the displacement of oil by water. Thus, the water flooding combined with EM heating is a viable method for oil recovery. We consider a simple mathematical model describing this experiment consisting of two balance laws for energy and water mass. The goal is to use Duhamel’s Principle and the Theory of Conservation Laws to find semi-analytical solutions of this simplified model. We use the principle solve the energy balance equation of convection-reaction-diffusion type for heat transport problem in a porous medium in the presence of a source of electromagnetic waves. The balance equation for the mass of water is a nonlinear partial differential equation of first order of Buckley-Leverett type. It is solved using the Theory of Conservation Laws.

Abstract:
Ultrasound is used in many areas of medicine, including diagnostic imaging, therapy, lithotripsy, and surgery. The chapter gives a general description of ultrasound, its propagation, bioeffects, and measurement techniques. Potential biohazards of ultrasound are tissue heating, cavitation, acoustic radiation forces, and mechanical strain due to particle displacement. Any bioeffects produced by ultrasound in diagnostic applications have little consequence for the individual, as illustrated by its routine use in diagnostic foetal scanning, but surgical techniques destroy tissue on a macroscopic scale. There are separate sections which consider exposure, standards and give practical guidance measures for each of the four main areas of medical application. All applications of ultrasound in medicine have an impressive safety record, and the 3 W cm-2 limit for therapeutic ultrasound is the only safety criterion that has been formally adopted into current international standards.

Abstract:
AbstractThe structure of the Sun, with its energy generation and heating, creates convection and differential rotation of the outer solar plasma. This convection and rotation of the ionized plasma generates the solar magnetic field. This field and its variation spawn all of the solar activity: solar active regions, flares, jets, and coronal mass ejections (CMEs). Solar activity provides the origin and environment for both the impulsive and gradual solar energetic particle (SEP) events. This chapter introduces the background environment and basic properties of SEP events, time durations, abundances, and solar cycle variations.

Abstract:
This paper provides a solution for two-dimensional heating over a rectangular region on a homogeneous plate. It has application to verification of numerical conduction codes as well as direct application for heating and cooling of electronic equipment. Additionally, it can be applied as a direct solution for the inverse heat conduction problem, most notably used in thermal protection systems for re-entry vehicles. The solutions used in this work are generated using Green’s functions. Two approaches are used which provide solutions for either semi-infinite plates or finite plates with isothermal conditions which are located a long distance from the heating. The methods are both efficient numerically and have extreme accuracy, which can be used to provide additional solution verification. The solutions have components that are shown to have physical significance. The extremely precise nature of analytical solutions allows them to be used as prime standards for their respective transient conduction cases. This extreme precision also allows an accurate calculation of heat flux by finite differences between two points of very close proximity which would not be possible with numerical solutions. This is particularly useful near heated surfaces and near corners. Similarly, sensitivity coefficients for parameter estimation problems can be calculated with extreme precision using this same technique. Another contribution of these solutions is the insight that they can bring. Important dimensionless groups are identified and their influence can be more readily seen than with numerical results. For linear problems, basic heating elements on plates, for example, can be solved to aid in understanding more complex cases. Furthermore these basic solutions can be superimposed both in time and space to obtain solutions for numerous other problems. This paper provides an analytical two-dimensional, transient solution for heating over a rectangular region on a homogeneous square plate. Several methods are available for the solution of such problems. One of the most common is the separation of variables (SOV) method. In the standard implementation of the SOV method, convergence can be slow and accuracy lacking. Another method of generating a solution to this problem makes use of time-partitioning which can produce accurate results. However, numerical integration may be required in these cases, which, in some ways, negates the advantages offered by the analytical solutions. The method given herein requires no numerical integration; it also exhibits exponential series convergence and can provide excellent accuracy. The procedure involves the derivation of previously-unknown simpler forms for the summations, in some cases by virtue of the use of algebraic components. Also, a mathematical identity given in this paper can be used for a variety of related problems.

Abstract:
The numerical investigation of laminar natural convection of viscoplastic fluid in a two dimensional square enclosure has been reported in this work. The enclosed fluid is subjected to partial bi-heating from the bottom wall and symmetrical cooling from the sides under steady condition. Yield stress fluid has been heated through two heaters symmetrically placed on the either side of the centre of the bottom wall of the square enclosure. The viscoplastic fluid is the one which requires a minimum critical stress called yield stress to flow otherwise behave as a solid, have been modeled with Herschel–Bulkley model. Such fluids have significant technological relevance due to its wide application ranging from cosmetics products, food processing industries, pharmaceuticals to natural occurring like flow of debris and lava. The solution of governing partial differential equations has been approached using finite volume based formulation. Non uniform set of grid has been used. The effects of yield stress, heat flux, and power law index on the flow and thermal characteristics of the free convection of Herschel-Bulkley fluids have been studied for a particular value of Prandtl number. The flow and thermal fields have been investigated for the following ranges of conditions: Rayleigh number varies between 103 and 106 whereas power law index ranges from 0 to 1. The heat transfer characteristic has been depicted with the help of isotherms and the flow field has been illustrated by streamlines. The onset of convection is substantially delayed due to presence of yield stress of the fluid. This results in enhanced critical Rayleigh number for onset of convection. With increase in the Yield number in turn yield stress, results in the weakening of heat transfer through convection and at a particular relatively higher value of Yield number the heat transfer is solely taken place by conduction mode. Due to the symmetry in both heating and boundary conditions, the obtained isotherms and streamlines of the right half are symmetrical to the left half of the square enclosure. The conductive mode of heat transfer becomes dominated by increasing yield stress and reducing Ra and vice versa. The simultaneous presence of yielded and unyielded region presents an interesting pattern in the convection zone. Furthermore, it can be seen that rise in heat flux, in turn Ra, promotes the buoyancy driven circulation of viscoplastic fluid i.e. enhances natural convective heat transfer. In addition, the effect of power law index has been investigated. Power law index has little effect on thermal distribution and flow field.

Abstract:
COVID-19 may have forever changed our world. Given the limited space and air circulation, potential infections on public transportation could be concerningly high. Accordingly, this study has two objectives: (1) to understand air circulation patterns inside the cabins of buses; and (2) to test the impact of different technologies in mitigating viruses from the air and on surfaces inside bus cabins. For the first objective, different devices, metrics and experiments (including colored smoke; videotaping; anemometers; pressure differentials; particle counts; and 3D numerical simulation models) were utilized and implemented to understand and quantify air circulation inside different buses, with different characteristics, and under different operating conditions (e.g. with windows open and shut). For the second objective, three different live prokaryotic viruses were utilized: Phi6, MS2 and T7. Various technologies (including positive pressure environment inside the cabin, HEPA filters with different MERV ratings, concentrated UV exposure with charged carbon filters in the HVAC systems, center point photocatalytic oxidation technology, ionization, and surface antiviral agents) were tested to evaluate the potential of mitigating COVID-19 infections via air and surfaces in public transportation. The effectiveness of these technologies on the three live viruses was tested in both the lab and in buses in the field. The results of the first objective experiments indicated the efficiency of HVAC system designs, where the speed of air spread was consistently much faster than the speed of air clearing. Hence, indicating the need for additional virus mitigation from the cabin. Results of the second objective experiments indicated that photocatalytic oxidation inserts and UVC lights were the most efficient in mitigating viruses from the air. On the other hand, positive pressure mitigated all viruses from surfaces; however, copper foil tape and fabrics with a high percentage of copper mitigated only the Phi6 virus from surfaces. High-temperature heating was also found to be highly effective in mitigating the different viruses from the vehicle cabin. Finally, limited exploratory experiments to test possible toxic by-products of photocatalytic oxidation and UVC lights inside the bus cabin did not detect any increase in levels of formaldehyde, ozone, or volatile organic compounds. Implementation of these findings in transit buses, in addition to the use of personal protective equipment, could be significantly valuable for protection of passengers and drivers on public transportation modes, possibly against all forms of air-borne viruses.
