The velocity field of a fluid flow in an unbounded domain, R, in which the spin of fluid elements is nonzero only within a bounded subdomain, Ri---namely, the interior of a sphere of radius, a---is simulated by equation-based modeling. A change of independent variable motivated by Kelvin ... Read More

When acoustic applications include small geometries, i.e. mm/submillimeter range, so-called thermoviscous effects can greatly affect the pressure response. This paper deals with acoustic topology optimization of such miniature structures with thermoviscous effects taken into account. ... Read More

In this work we report a numerical model of a Rotating Disk Electrode (RDE) voltammetry in a finite size domain. Thus, explaining the discrepancy of the diffusion coefficient obtained from the experimental rotating speed, with respect to the literature data. We achieved a very good ... Read More

Our atmosphere, land, and water are being continuously besieged by pollutants caused by such events as heavy metals leaching from mine tailing ponds, chemical spills from railroad and truck tanker accidents, and petroleum pipeline failures, to name just a few. These environmental ... Read More

For the numeric investigations of the high temperature compact heat exchanger two numeric models with and without the regards of the velocity field development were used. The results of the comparison of the numeric and experimental data confirm the necessity of regarding the velocity ... Read More

An app built with the COMSOL Multiphysics® software allows both expert and beginner users to carry out parametric simulations thanks to flexible and user-friendly customized interfaces. Many people, with or without expertise in numerical analysis, can now access, exploit and share ... Read More

Array-based technologies are important for many applications in drug discovery, microbiology and cell biology. A large-scale array of single cells allows high-throughput monitoring of behaviors of individual cells in parallel, avoiding the lack of cell specificity inherent to bulk ... Read More

The present author’s specialty is Aerodynamics, a field in which problems in unbounded fluid domains are common. The COMSOL Multiphysics® simulation software's support of Infinite Elements is attractive as a tool for addressing such problems. Be that as it may, neither the COMSOL ... Read More

Particle velocimetry using image analysis is an effective non-intrusive method used for fluid velocity field estimation in micro-channels. We use COMSOL with MATLAB to generate velocity fields for micro-channel designs and then calculate changes in particle position for given imaging ... Read More

Laser additive manufacturing has become an interesting field of engineering which is revolutionizing industrial processes. Selective Laser melting (SLM) is a widely used additive manufacturing technique for 3D printing of metal structures. This process has a particular complexity in ... Read More
