Radio-Frequency ablation (RFA) has received a considerable interest as a minimally invasive treatment technique used for destruction of a variety of primary and metastatic hepatic tumors. A parametric study of hepatic radio-frequency ablation using three-dimensional numerical models has ... En savoir plus

A new microwave cavity for the regeneration of DPF regeneration was proposed and COMSOL Multiphysics® FEM model was used to investigate heating properties of the Silicon Carbide (SiC) based DPF. Electric field profile and thermal profile of the microwave cavity and DPF was established ... En savoir plus

Simplistic, 1D analytical calculations in electro-magneto-hydrodynamics are attractive to technologists and researchers given the computational resources and time required by 3 dimensional F.E. (Finite Element) tools. However, such analytical calculations need to be checked against 3D ... En savoir plus

This paper reports the simulation of micro-electro-mechanical system (MEMS) cleanroom for the purpose of determining the effect of particulate contaminants on the static stress response of cantilever type MEMS devices, such as high precision MEMS pressure sensor. The contaminant presence ... En savoir plus

The extensional flow of viscoelastic flow is encountered during fibre spinning processes. A variety of polymers such as polyesters, polyacrylonitrile, rayon, acrylic, spandex etc are manufactured using this process. In the spinning process, polymer melt/ solution is extruded in the form ... En savoir plus

Increased light scattering have been found to improve the short-circuit current of photovoltaic devices. In this paper we have tried to optimize the dimensions of ZnO nanorods to achieve this. Scattering efficiency of these nanorods was evaluated by solving Maxwell’s electromagnetic ... En savoir plus
