Cerebral vasospasm is a complication of subarachnoid hemorrhage and other neurosurgical emergencies that reduce blood flow to the brain. Part of the approach to management of vasospasm is to improve flow through the stenotic areas by reducing by decreasing blood viscosity and enhancing ... En savoir plus
A major issue in predicting and controlling (via design) absorption properties of rigid porous media is the determination of the frequency-dependent effective density and compressibility tensors. Unlike previous research efforts which employ in-house and, oftentimes, multiple numerical ... En savoir plus
The aim of the present work is to implement in COMSOL Multiphysics a multiphase fluid flow model in porous media, also known in the oil reservoir engineering literature as a black oil model, using a standard finite element approach. In particular, we are interested to apply this model ... En savoir plus
Transport of microorganisms through porous media governs many phenomena in bioremediation of environmental pollution problems and microbial enhanced oil recovery. The aim of this work is to investigate the effects of some transport parameters on breakthrough curves as well as on spatial ... En savoir plus
To investigate the thermal-mechanical behavior of oceanic transform faults, we calculate 3-D steady-state incompressible mantle flow and heat transport using COMSOL Multiphysics. Our model incorporates a nonlinear viscous rheology with a visco-plastic approximation to simulate ... En savoir plus
We have simulated the copper ion concentration and internal electric field profiles in a dielectric material by solving the transient continuity/Poisson equations using COMSOL Multiphysics. We have shown that failure of dielectrics can be modeled if we assume that failure in Cu/SiO2/Si ... En savoir plus
This paper presents a 3D finite element model in COMSOL for the electro-thermal analysis of high power light emitting diodes (LEDs). The proposed model and implementation approach require basic electrical and optical parameters that may be experimentally derived with the aid of advanced ... En savoir plus
A micromirror or a torsional actuator in general has been proven to be one of the most popular actuators fabricated by Micro-Electro-Mechanical System (MEMS) technology in many industrial and biomedical applications such as RF switches, a laser scanning display, an optical switch matrix, ...

Recently, the advanced plasma tools have been using very high frequency power sources (>100 MHz) and their combination to excite plasma utilized in semiconductor technology. This approach is evoking the regimes that are less understood and currently a subject to many studies and ... En savoir plus
Tunnels and their detection have been a problem in warfare since the ancient world. Recent events have highlighted the ongoing problems of tunnels and the difficulties in locating them, not only in military situations, but also in law enforcement and homeland security applications as ...
