How to Compute Residence Time in Flow Models with COMSOL®

June 1, 2021

You can compute residence time in flow problems using the Particle Tracing Module. Get the details in this blog post.

How to Analyze Turbomolecular Pumps with COMSOL Multiphysics®

January 12, 2021

Modeling gas flow in a turbomolecular pump calls for specialized numerical methods, because at such low pressures, the gas molecules rarely collide with each other.

What Formulation Should I Use for Particle Tracing in Fluids?

December 4, 2020

The COMSOL® software gives you 4 equation formulation options when modeling particle tracing in fluids: Newtonian; Newtonian, first order; Newtonian, ignore inertial terms; and Massless.

Speeding Up DNA Separation in a Microchannel via Simulation

May 9, 2019

DNA separation takes a long time using traditional methods. Now, researchers from the Missouri University of Science and Technology have found a faster way to get the job done.

Keynote Video: Designing Improved Heart Pumps with Simulation

December 5, 2018

Abbott Laboratories designed “the most complex machine ever implanted into a human being” — an LVAD for heart failure patients — using multiphysics modeling. The result? Saved lives.

Evaluating Static Mixer Performance with a Simulation App

June 8, 2016

In this blog post, we go over the setup of an app designed to quantitatively and qualitatively analyze the performance of a static mixer using the Particle Tracing Module.

Preventing Airborne Infection with CFD Modeling

December 2, 2015

Healthcare-associated infections affect millions of people around the globe. Airborne bacteria is one cause of patient infections that can be prevented with efficient ventilation system designs.

Dielectrophoretic Separation

January 23, 2015

Dielectrophoresis is a phenomenon in which an electric field is used to control the movement of electrically neutral particles. Learn about how to model this effect in both DC and AC fields.
