This paper summarizes the numerical contribution to a project for the detection of bioparticles present in a small volume of a liquid sample. Dielectrophoresis (DEP) is used to enhance their transport toward the surface of a detector. The mathematical model is composed of the electrokinetics equation for the DEP force-field calculation, and the advection-diffusion equation for the particle ...

In this paper, we create models with the use of COMSOL Multiphysics to predict evolution of temperatures and crust formation in meat during barbecuing and oven roasting. Sensitivity to parameters is analysed and predictions are compared to experimental data from literature.

We present simulations of drops spreading on heterogeneous surfaces. The droplet height is the solution of a time-dependent non-linear fourth order partial differential equation, which is solved using COMSOL Multiphysics. In the fully wetting case, we compare our results with experimental data and with previous results reported in the literature. The simulation results reveal how ...

In this paper, an investigation of heat and mass transfer in fabrics used in the manufacture of comfortable sportswear is presented. It is based on a model which is described by partial differential equations representing the mass balance of free and adsorbed water and vapour and the heat balance in the fabric. The model involves several unknown physical and transfer parameters. Two ...

Thermoplastic polymers are frequently used in several industries, and represent the most important group of polymeric materials. During the injection moulding process, the cooling phase including solidification is often the most significant part of the manufacturing cycle. In this paper we study the coupling phenomena between the crystallization and the thermal kinetics in the polymer ...

In this paper, we investigate the compressional wave generation in droplets and use different techniques to correlate the compressional wave generation to the shape of the droplets. Results show a good correlation between eigenmodes predicted by the theory and those experimentally observed.

In this paper, we present the modeling of catalytic reactions under non-steadystate conditions. Particularly, we study the Fisher-Tropsch reaction in a pulse reactor.

The most common case of crevice corrosion occurs on passive materials such as stainless steels, in oxidizing-chloride environments. A flexible crevice propagation model has been developed to allow parametric studies of the solution. Our main results allow us to establish diagrams of stability of solid and gas phases within the crevice and to evaluate the influence of the external ...

The knowledge of the light propagation through a nanometer-size aperture is crucial for Scanning Optical Near Field Microscopy (SNOM). In this work, we address a numerical study of the transmitted electric field through a SNOM probe. The influence of the wavelength is also studied. Our results show that the logarithmic power decreases linearly as a function of the aperture size, and the ...
