This paper presents a numerical study of the deposition of submicron charged spherical particles caused by convection, Brownian and turbulent diffusion in a pipe with a smooth wall and with a cartilaginous ring wall structure (see figure). The model is supposed to describe deposition of ... Mehr lesen
We present an optimization procedure to optimize the maximum coupling of free space optical wave to surface plasmon. Shape derivative from shape sensitivity analysis is calculated, and the corresponding partial derivatives of the objective functional with respect to finite number of ... Mehr lesen
This work analyzes the spin-diffusion dominated explanation for spin-up bulk flows in ferrofluid filled cylinders, with no free surface, subjected to a uniform rotating magnetic field. COMSOL results are compared to experimental results and analytical results. Simulating ferrofluid spin ... Mehr lesen
Hazardous for the transmission lines is not only the static ice load, but also the aerodynamic instability of iced cables. It can lead to large amplitude oscillations at low frequencies. Also, twisting due to asymmetrical iced cables may increase the fatigue rate. In extreme events, ... Mehr lesen
Lab-on-a-chip devices for cell culturing are becoming imperative in order to satisfy the needs for point-of-care or decentralized laboratory testing. Towards that goal we have developed miniaturized membrane based cell culture chambers for use within the field of chromosome analysis. The ... Mehr lesen
We discuss the use of COMSOL Multiphysics 3.4 in the aerodynamic optimization process of the UNLV solarpowered UAV. We also address the use of COMSOL’s Multiphysics ability and how it was used within the scope of the project. In particular we highlight the development of wingtip devices, ... Mehr lesen
This work deals with the quantification of the CO2 transfer rate from a bubble to the surrounding liquid in a bubble column. A model is successfully developed using COMSOL Multiphysics. The validated model is used to study the enhancement influence of chemical reactions on the transfer ... Mehr lesen
Dielectrophoresis is a phenomenon in which a force is exerted on a dielectric particle when it is subjected to a non-uniform electric field. In this research, we analyze dielectrophoretic (DEP) force using a geometry containing two electrodes, one with SiO2 and one without, with a gap ... Mehr lesen
The aim of the proposed device is to overcome the typical drawbacks of MHD generators, such as the needed of a very high external magnetic field, the strong dependency of the efficiency by the temperature of the fluid, and the deterioration of the electrodes that are in contact with the ...

A new simple air-cooled inverter design is numerically investigated using COMSOL Multiphysics® software. The thermal-fluid analysis is based on a three-dimensional conjugate heat transfer model in which the flow field is assumed to be laminar. A rigorous mesh convergence was performed to ... Mehr lesen
