We present a study of an optofluidic biosensor. The sensor operates in a transmission mode wherein detection is based on a shift in the transmission spectrum caused by the contrast in refractive index between the carrier fluid and the target biomaterial. We study the behavior of the ... En savoir plus
The use of Microwave/RF energy on cancer cells is explored for tumor ablation using medium power level ranging between a few Watts to about 50 Watts. In this research, low power levels, less than 100 mWatt, are used to evaluate the effect of this energy on Uveal melanoma cells by ... En savoir plus
Atherosclerosis causes the deposition of plaque on the inner walls of arteries, which leads to restricted blood flow. Using the balloon angioplasty procedure, stents can be inserted and expanded in the atherosclerotic artery. We used COMSOL Multiphysics Structural Mechanics, Solid Stress ... En savoir plus
For medical diagnostic purposes there is an increasing need for non-(or minimal) invasive techniques to measure all kinds of parameters that can provide insight in the functioning of cells, organs or organ systems. Currently, Impedance Cardiography (ICG) is used for measurements of the ... En savoir plus
COMSOL Multiphysics was used to solve a phonon Boltzmann transport equation (BTE) for nanoscale heat transport problems. One dimensional steady-state and transient BTE problems were successfully solved based on finite element and discrete ordinate methods for spatial and angular ... En savoir plus
This work demonstrated the importance and feasibility of experimental image to simulation workflow. The workflow is successfully applied to a food processing study, where multiphysics and multiscale modeling based on 3D experimental image reconstruction contributes to the preservation of ...

One way of storing thermal energy is through the use of latent heat energy storage systems. One such system, composed of a cylindrical container filled with paraffin wax, through which a copper pipe carrying hot water is inserted, is presented in this paper. It is shown that the physical ... En savoir plus
Heat transfer from a sphere having a uniform temperature and falling axially in a cylindrical tube filled with an incompressible power-law liquid is numerically investigated. The governing equations for simultaneous flow around a confined sphere and heat transfer to power-law fluids were ... En savoir plus
Most reactor designs are based on pseudo homogeneous models. This paper studies the COMSOL simulation of a packed bed reactor using a 2-D heterogeneous model. The case considered was a packed reactor with spherical catalyst for oxidation of o-xylene in air to phthalic anhydride. Large ... En savoir plus
The presence of a moving fluid in a porous rock modifies its mechanical response. Poroelasticity explains how the fluid inside the pores bears a portion of the total load supported by the rock. The remaining part of the load is supported by the elastic skeleton, which contains a laminar ... En savoir plus
