Abstract:
In a triple plasma device, the injection of electron current from the source chamber to the target chamber causes the formation of a potential double layer. At a low current density, the space charge of the injected current produces a virtual cathode-type potential double layer. This double layer is stable and various wave instabilities are observed to associate with this double layer. As the current density is increased, the double layer becomes unstable and a moving double layer results. As the current density is increased further, the enhanced ionization causes the neutralization of the space charge of the electron beam and the ‘beam plasma discharge’ is ignited.

Abstract:
Abstract. An auroral flux tube is modelled from the magnetospheric equator to the ionosphere using Vlasov simulations. Starting from an initial state, the evolution of the plasma on the flux tube is followed in time. It is found that when applying a voltage between the ends of the flux tube, about two thirds of the potential drop is concentrated in a thin double layer at approximately one Earth radius altitude. The remaining part is situated in an extended region 1–2 Earth radii above the double layer. Waves on the ion timescale develop above the double layer, and they move toward higher altitude at approximately the ion acoustic speed. These waves are seen both in the electric field and as perturbations of the ion and electron distributions, indicative of an instability. Electrons of magnetospheric origin become trapped between the magnetic mirror and the double layer during its formation. At low altitude, waves on electron timescales appear and are seen to be non-uniformly distributed in space. The temporal evolution of the potential profile and the total voltage affect the double layer altitude, which decreases with an increasing field aligned potential drop. A current–voltage relationship is found by running several simulations with different voltages over the system, and it agrees with the Knight relation reasonably well.

Abstract:
The method of regularised stokeslets is widely used to model microscale biological propulsion. The method is usually implemented with only the single-layer potential, the double-layer potential being neglected, despite this formulation often not being justified a priori due to nonrigid surface deformation. We describe a meshless approach enabling the inclusion of the double layer which is applied to several Stokes flow problems in which neglect of the double layer is not strictly valid: the drag on a spherical droplet with partial-slip boundary condition, swimming velocity and rate of working of a force-free spherical squirmer, and trajectory, swimmer-generated flow and rate of working of undulatory swimmers of varying slenderness. The resistance problem is solved accurately with modest discretisation on a notebook computer with the inclusion of the double layer ranging from no-slip to free-slip limits; the neglect of the double-layer potential results in up to 24% error, confirming the importance of the double layer in applications such as nanofluidics, in which partial slip may occur. The squirming swimmer problem is also solved for both velocity and rate of working to within a small percent error when the double-layer potential is included, but the error in the rate of working is above 250% when the double layer is neglected. The undulating swimmer problem by contrast produces a very similar value of the velocity and rate of working for both slender and nonslender swimmers, whether or not the double layer is included, which may be due to the deformation’s ‘locally rigid body’ nature, providing empirical evidence that its neglect may be reasonable in many problems of interest. The inclusion of the double layer enables us to confirm robustly that slenderness provides major advantages in efficient motility despite minimal qualitative changes to the flow field and force distribution.

Full text
Abstract:
A quantitative determination of the potential distribution in the Stern–Gouy double-layer model for clay–water–electrolyte systems is presented. The surface potential, Stern potential, thickness of the Gouy diffuse layer, and distribution of electrical potential can be computed by knowing the required parameters, such as the cation exchange capacity, specific surface area, electrolyte concentration, and valence, temperature, and permittivity of the solvent (pore fluid). The factors influencing the potential distribution in the double layer are discussed. To demonstrate the applications of the Stern–Gouy model, two examples are presented. In the first example, the relationship between the double-layer thicknesses and hydraulic conductivities of a natural soil permeated by different organic compounds is established. In the second example, the electric potential distributions of three natural clays are presented. It is anticipated that the Stern–Gouy double-layer model will find broader applications in geotechnical and environmental engineering practice as the principles and computation methods become more familiar to engineers. Key words : Stern–Gouy electrical double layer, clay–water–electrolyte systems, soil behaviour, hydraulic conductivity, sensitivity.

Abstract:
Several elliptic integrals related to the interaction energy between two dissimilar parallel plates (the potentials on the two plates are of the same sign) are expanded in several fast convergent series for lower and higher surface potentials, respectively. The number of series terms required to obtain the interaction energy with six significant figures is not more than four for the dimensionless surface potential from 0 to 20 if the series fit for the lower potential is combined with the series fit for the higher potential. The approximate expressions with different precisions can be obtained by retaining different series terms. The results of Devereux and de Bruyn are discovered to be incorrect when the surface potential is very low or very high.

Full text
Abstract:
Layer potential operators associated to elliptic partial differential equations have been an object of investigation for more than a century, due to their contribution in the solution of boundary value problems through integral equations. In this Licentiate thesis we prove the boundedness of the double layer potential operator on the Hilbert space of square integrable functions on the boundary, associated to second order uniformly elliptic equations in divergence form in the upper half-space, with real, possibly non-symmetric, bounded measurable coefficients, that do not depend on the variable transversal to the boundary. This uses functional calculus of bisectorial operators and is done through a series of four steps. The first step consists of reformulating the second order partial differential equation as an equivalent first order vector-valued ordinary differential equation in the upper halfspace. This ordinary differential equation has a particularly simple form and it is here that the bisectorial operator corresponding to the original divergence form equation appears as an infinitesimal generator. Solving this ordinary differential through functional calculus comprises the second step. This is done with the help of the holomorphic semigroup associated to the restriction of the bisectorial operator to an appropriate spectral subspace; the restriction of the operator is a sectorial operator and the holomorphic semigroup is well-defined on the spectral subspace. The third step is the construction of the fundamental solution to the original divergence form equation. The behaviour of this fundamental solution is analogous to the behaviour of the fundamental solution to the classical Laplace equation and its conormal gradient of the adjoint fundamental solution is used as the kernel of the double layer potential operator. This third step is of a different nature than the others, insofar as it does not involve tools from functional calculus. In the last step Green’s formula for solutions of the divergence form partial differential equation is used to give a concrete integral representation of the solutions to the divergence form equation. Identifying this Green’s formula with the abstract formula derived by functional calculus yields the sought-after boundedness of the double layer potential operator, for coefficients of the particular form mentioned above.

Full text
Abstract:
Abstract The dissertation considers the time fractional diffusion equation (TFDE) with the Dirichlet boundary condition in the sub-diffusion case, i.e. the order of the time derivative is α ∈ (0,1). In the thesis we have studied the solvability of TFDE by the method of layer potentials. We have shown that both the single layer potential and the double layer potential approaches lead to integral equations which are uniquely solvable. The dissertation consists of four articles and a summary section. The first article presents the solution for the time fractional diffusion equation in terms of the single layer potential. In the second and third article we have studied the boundary behaviour of the layer potentials for TFDE. The fourth paper considers the spline collocation method to solve the boundary integral equation related to TFDE. In the summary part we have proved that TFDE has a unique solution and the solution is given by the double layer potential when the lateral boundary of a bounded domain admits C1 regularity. Also, we have proved that the solution depends continuously on the datum in the sense that a nontangential maximal function of the solution is norm bounded from above by the datum in L2(ΣT). If the datum belongs to the space H1,α/2(ΣT), we have proved that the nontangential function of the gradient of the solution is norm bounded from above by the datum in H1,α/2(ΣT).

Abstract:
Water scarcity is a global concern that impacts many developing countries, forcing people to depend on unclean water sources for domestic, agricultural, and industrial needs. Wastewater is an alternative water source that contains nutrients needed for crop growth. Wastewater reuse for agriculture can cause public health problems because of human exposure to pathogens. Pathogen monitoring is essential to evaluate the compliance of wastewater with established World Health Organization (WHO) and U.S. Environmental Protection Agency (EPA) wastewater reuse guidelines. Indicator organisms are commonly used to detect pathogens in water and wastewater because they are quick and easy to measure, non-pathogenic, and have simple and inexpensive methods of detection. The objective of this research was to develop a modified double agar layer assay method that can be conducted in the field to quantify bacteriophage to assess the quality of wastewater for agricultural reuse. Results from the modified double agar layer assay were used to investigate the potential of somatic coliphage as an indicator organism for assessing the potential presence of enteric viruses in developing world treated wastewater, and to use the criteria of a good indicator organism to compare the potential of two commonly used indicator organisms, somatic coliphage and fecal coliforms, as an indicator of enteric viruses in wastewater. A modified EPA double agar layer method was developed and deployed in a developing world rural community to effectively quantify the concentration of somatic coliphage in a community managed wastewater treatment system composed of a Upflow Anaerobic Sludge Blanket (UASB) reactor followed by two maturation lagoons. The modified method served as a good indicator of enteric viruses in the water. Somatic coliphages were easily detected and quantified in the field setting using a modified double agar layer method. Somatic coliphage was found to be a potential indicator for enteric viruses rather than fecal coliforms because of their similarity in characteristics and resistances to wastewater treatment. The concentration of somatic coliphage was only reduced by 1.05 log units across the two series maturation lagoon system. Previous literature suggested removal would range from 2.1 to 4.6 log units. Influent wastewater (previously treated by an UASB reactor) had a concentration of 4.38 E+06 PFU/ 100 mL (standard deviation = ±3.7E+06, n = 9) and the treated effluent contained 3.90 E+05 PFU/100 mL (standard deviation = ± 4.5E+05, n = 8) of somatic coliphages. Results suggest that somatic coliphage is a good potential indicator for enteric viruses in wastewater but further research needs to be done.

Abstract:
We prove the existence of Hp(D)-limit of iterations of double layer potentials constructed with the use of Hodge parametrix on a smooth compact manifold X, D being an open connected subset of X. This limit gives us an orthogonal projection from Sobolev space Hp(D) to a closed subspace of Hp(D)-solutions of an elliptic operator P of order p ≥ 1. Using this result we obtain formulae for Sobolev solutions to the equation Pu = f in D whenever these solutions exist. This representation involves the sum of a series whose terms are iterations of double layer potentials. Similar regularization is constructed also for a P-Neumann problem in D.

Full text
Abstract:
The Double-TOP trap is a new type of magnetic trap for neutral atoms, and is suitable for Bose-Einstein condensates (BECs) and evaporatively cooled atoms. It combines features from two other magnetic traps, the Time-averaged Orbiting Potential (TOP) and Ioffe-Pritchard traps, so that a potential barrier can be raised in an otherwise parabolic potential. The cigar-like cloud of atoms (in the single-well configuration) is divided halfway along its length when the barrier is lifted. A theoretical model of the trap is presented. The double-well is characterised by the barrier height and well separation, which are weakly coupled. The accessible parameter space is found by considering experimental limits such as noise, yielding well separations from 230 [mu]m up to several millimetres, and barrier heights from 65 pK to 28 [mu]K (where the energies are scaled by Boltzmann�s constant). Potential experiments for Bose-Einstein condensates in this trap are considered. A Double-TOP trap has been constructed using the 3-coil style of Ioffe-Pritchard trap. Details of the design, construction and current control for these coils are given. Experiments on splitting thermal clouds were carried out, which revealed a tilt in the potential. Two independent BECs were simultaneously created by applying evaporative cooling to a divided thermal cloud. The Double-TOP trap is used to form a linear collider, allowing direct imaging of the interference between the s and d partial waves. By jumping from a double to single-well trap configuration, two ultra-cold clouds are launched towards a collision at the trap bottom. The available collision energies are centred on a d-wave shape resonance so that interference between the s and d partial waves is pronounced. Absorption imaging allows complete scattering information to be collected, and the images show a striking change in the angular distribution of atoms post-collision. The results are compared to a theoretical model, verifying that the technique is a useful new way to study cold collisions.

Abstract:
La limitation des rejets en CO₂ associés aux normes européennes antipollution de plus en plus sévères ont conduit les constructeurs automobiles à innover dans de nouveaux concepts de combustion, dans l’objectif d’augmenter le rendement des moteurs essence conventionnels. La combustion de type Partiellement Prémélangée, communément appelée Gasoline Partially Premixed Combustion (soit GPPC) semble être l’un des possibilités pour répondre à ces problématiques, en particulier s’il était possible d’atteindre un rendement proche des rendements Diesel avec des émissions polluantes plutôt de type moteur à allumage commandé et qui pourraient donc être traitées par systèmes de post-traitement classiques. Cette étude vise, par une approche expérimentale, à comprendre les processus physiques qui permettent d’optimiser ce nouveau mode de combustion, en particulier en termes de préparation du mélange et de déroulement de la combustion proprement dite. La première partie de ce travail a consisté en la détermination de l’impact des différentes conditions thermodynamiques, de la stratégie d’injections et du taux de dilution sur le déroulement de la combustion à partir de données obtenues sur un moteur opaque. Trois modes de dégagements de chaleur très distincts ont été sélectionnés, l’un représentant la configuration optimale en termes de rendement et d’émissions polluantes à partir d’expériences réalisées sur moteur monocylindre à fort taux de compression et avec une chambre typée Diesel. Des techniques de diagnostics optiques ont été mises en place sur un moteur identique mais à accès optiques dans l’objectif d’isoler tout particulièrement l’impact du phasage de la seconde injection sur le déroulement de la combustion. L’étude de la propagation liquide du spray lors de l’injection, de l’interaction entre l’air et le carburant lors du processus de formation du mélange et de la phase d’oxydation du carburant a ainsi pu être réalisée et a permis de valider les hypothèses émises lors des essais sur moteur opaque pour expliquer les processus de combustion et donner des pistes de contrôle de ce type de combustion
Carbon dioxide (CO₂) and other pollutant emission limitations are more and more rigorous. These limits conduct cars manufacturers to study new combustion concept, in order to increase conventional gasoline engine efficiencies. Gasoline Partially premixed combustion concept (GPPC) seems to have the potential to reach these objectives, in other terms an efficiencies comparable to diesel engine by with emissions of gasoline engine, which mean a low cost after-treatment system. This study investigates, by an experimental approach, the physical process responsible on controlling this combustion concept and by the way improves it. This will be done by studying the mixture preparation and the combustion behaviour. The first part of this work concerns on determining the impact of in-cylinder thermodynamic conditions, injection strategy and the dilution rate on combustion behaviour using a single cylinder all metal engine. Three distinctive heat release rates were selected; where one represent the optimized injection phasing in term of efficiencies and pollutant emissions. The second part was dedicated to studying the process involved in GPPC combustion mode by optical diagnostic techniques on single cylinder optical access diesel engine. The impact of second injection phasing, fuel and air interaction and also the fuel combustion process allowed the validation of hypothesis emitted in the first part to explain the combustion behaviour and give ways to control this combustion mode

Abstract:
Allegory is a figure of speech that is frequently used in Christian religious discourse, not only in the Christian Scriptures, but also in theological and homiletic literature throughout history. However, its use has also been viewed with suspicion by various schools of Christian thought. That is, allegory as a figure of speech is perceived as both being a useful tool for religious discourse and beset by limitations. This double-sided perception of the utility of allegory is rooted in the cognitive complexities that the comprehension of allegory involves, according to Unger (2017). Processing allegory involves our ability to detect and process multiple layers of communication in one act of ostensive communication. Thus, allegory has the potential for being effective for communicating complex thoughts in an elegant and effective way; at the same time, it runs the risk of inviting the audience to overinterpret the communication event.

Abstract:
In the present paper a new model is proposed for electric double layer (EDL) overlapped in nanochannels. The model aimed to obtain a deeper insight of transport phenomena in nanoscale. Two-dimensional Nernst and ionic conservation equations are used to obtain electroosmotic potential distribution in flow field. In the proposed study, transport equations for flow, ionic concentration and electroosmotic potential are solved numerically via finite volume method. Moreover, Debye-Hu¨ckle (DH) approximation and symmetry condition, which limit the application, are avoided. Thus, the present model is suitable for prediction of electroosmotic flows through nanochannels as well as complicated asymmetric geometries with large nonuniform zeta potential distribution. For homogeneous zeta potential distribution, it has been shown that by reduction of channel height to values comparable with EDL thickness, Poisson-Boltzmann model produces inaccurate results and must be avoided. Furthermore, for overlapped electric double layer in nanochannels with heterogeneous zeta potential distribution it has been found that the present model returns modified ionic concentration and electroosmotic potential distribution compare to previous EDL overlapped models due to 2D solution of ionic concentration distribution. Finally, velocity profiles in EDL overlapped nanochannels are investigated and it has been showed that for pure electroosmotic flow the velocity profile deviates from the expected plug-like profile towards a parabolic profile.

Abstract:
We developed a 2D electric double layer model for biological nanochannels based on the linearlized Poisson-Boltzmann equation with arbitrary surface potential. Time dependent adsorption kinetics was used in the model to examine the variation of electric double layer distribution and compare with that from the classical model. Based on the 2D model, EDL interaction for heavily patched arbitray surface potential was found to be much weaker in such biological nanochannels. Channel end effects are also found to be significant and not negligible.

Abstract:
Most analytical models for the electrokinetic flow were developed for pipe or channel sizes sufficiently large or the zeta-potential sufficiently small for the application of Boltzmann distribution. With increasing interest in nano-fluidic flows, the effect of overlapping electrical double layer (EDL), which means that the pipe size is similar to or less than the Debye length, plays a more and more important role in the flow. The Boltzmann equation, which has been widely used to describe the ionic distribution in the EDL in the semi-infinite domain, is not applicable for the case of the overlapping EDL due to its limited flow space. The Nernst equation, instead, has been suggested in the literature.

Abstract:
Joule heating of liquid films in the presence of an externally applied electric field is influenced by the formation of the electric double layer. The thickness and charge distribution inside the electric double layer determine the extent of interaction of the charge in the electric double layer with the externally applied electric field and the Joule heating of the electrolyte layer. For this reason, the effects of externally applied electric field (both parallel and along the normal to the surface) on the electric double layer are being studied in the present paper. In the absence of the externally applied electric field, the distribution of the electric potential in the double layer is given by Poisson equation. Assuming Boltzmann distribution for the ionic concentration in the double layer, one arrives at Poisson-Boltzmann equation for the electric potential distribution. The externally applied electric field changes this electric potential distribution. Hence, the contribution of the externally applied electric field is studied by including it in the Poisson-Boltzmann equation.

Abstract:
Analysis of a suspension of microorganisms is important in environmental and biomedical engineering. Previous studies had problems of high computational load in simulating many-body interaction of non-spherical swimmers. In this study, we propose a boundary element method (BEM), based on the double-layer representation, for calculating interactions of two squirmers in Stokes flow regime. By comparing the trajectories of squirmers calculated by both single- and double-layer representations, we show the accuracy of the method. The developed method has potential to deal with many-body interactions of non-spherical microorganisms.
