An experimental LED light composed of a multi-chip LED-module, a LED driver and an efficient heat sink, was investigated using COMSOL Multiphysics software and the Heat Transfer Module. In an LED light heat is mainly generated in the LEDs but some amount of heat is generated also in the ... 詳細を見る

This contribution is devoted to the mathematical modeling of the AC electroosmotic micropumps in COMSOL Multiphysics and Matlab. The mathematical model involves the microchannel surroundings and several AC-voltage driving modes. The weak form has been used for handling singularities and ... 詳細を見る

Microfabricated planar interdigitated electrodes can detect and analyze cells or particles giving an impedance-based characterization. This method presents several advantages: real-time detection, label-free analysis, non-invasive sensing, easiness of integration and high-throughput ... 詳細を見る

One viable alternative to non-renewable fossil fuels is the fuel cell. A special class of FC i.e. Proton Exchange Membrane Fuel Cell (PEMFC) has been investigated during the present study. Membrane is a very important part of a PEMFC as most ohmic losses occurs here and limits the ... 詳細を見る

A 2-D unsteady viscous flow around two cylinders is studied by numerical solutions of the unsteady Navier-Stokes equations with a finite element formulation using COMSOL Multiphysics®. The results of a numerical investigation of the Strouhal frequencies of two identical, stationary, ... 詳細を見る

Atherosclerosis in arteries is caused by the formation of stenosis : fatty depositions, on the artery wall. In current medicine, the practice is to observe the maximum percentage occlusion at any arbitrary cross-section and diagnose the patient on that basis, which might not always ... 詳細を見る

Heat transfer in a plane shear flow configuration consisting of two infinitely long parallel plates is considered. In laminar flows over undulated substrates eddies can be generated due to the kinematical constraints. A closed form analytical solution for the velocity field, based on ... 詳細を見る

Microchannel heat sinks designed for applications in electronic cooling and having microscale heat transfer combine the attributes of high material compatibility, high surface area per unit volume ratios, and large potential heat transfer performance with a highly sophisticated and ... 詳細を見る

Electrofluidic transport through a single walled carbon nanotube (SWCNT) is enhanced by electroosmosis. Electroosmosis is made possible in these devices by the combination of a large slip length within SWCNTs and the interfacial potential at the solution/nanotube interface. A ... 詳細を見る

We present numerical results involving microorganisms adhering to a plane surface submitted to a shear flow. The purpose is to have a better understanding of the removal mechanisms occurring during the cleaning in place of food processing equipments. The biological cell, i.e. the ... 詳細を見る
