How to Model Heat and Moisture Transport in Porous Media with COMSOL®

June 14, 2017

Modeling the transport of heat and moisture in porous media, like building envelopes and other construction materials, is a simple process with a predefined Heat and Moisture Transport interface.

Analyzing Heat and Mass Transfer During Cake Baking with Simulation

April 26, 2017

As you bake a cake, there are many complex heat and mass transport processes taking place behind the oven door. Take a closer look at the art and science involved in the cake baking process…

Modeling the Performance of an Evaporative Emission Control System

January 13, 2017

Researchers turned to COMSOL Multiphysics to model the adsorption and desorption in an evaporative emissions control system for enhanced automotive efficiency.

Study Contaminant Removal in Membrane Dialysis Devices with an App

December 15, 2016

For patients with renal failure, efficient dialysis treatment is vital. One point of focus is designing high-performance dialysis equipment that increases contaminant removal, improving treatments like hemodialysis. To accomplish this, you can study aspects of the hemodialysis process, such as membrane dialysis devices, with numerical modeling apps. These apps, like the one discussed here, enable users to more quickly analyze the effects of different inputs and improve designs.

Designing Effective Transdermal Drug Delivery Patches with Simulation

November 29, 2016

Transdermal drug delivery (TDD) patches continuously deliver drugs into the body for a certain amount of time. However, the skin is designed to keep out foreign substances, like drugs. To create a TDD patch that successfully bypasses this barrier, simulation can be used to study drug release and absorption into the skin. To analyze this process, Veryst Engineering created a TDD patch model with the COMSOL Multiphysics® software and compared the results to experimental data.

Studying the Migration of Mineral Oil Hydrocarbons in Food Packaging

November 17, 2016

Food packaging is often composed of recycled materials, like newspapers or plastic, which may contain residual mineral oil inks. Traces of these potentially hazardous substances leftover from the recycled materials can migrate from the packaging to the stored food. To account for this, one research team developed a numerical model to analyze the migration patterns of mineral oil hydrocarbons for various packaging situations. Compared to experimental studies, their approach offers a more efficient and cost-effective way of optimizing food safety.

Analyze a Vacuum Dryer’s Speed with Multiphysics Modeling

October 19, 2016

In certain food and pharmaceutical industries, different types of dryers are used to dry heat-sensitive products. Vacuum dryers offer one solution for removing water and organic solvents from these sensitive substances. For optimal vacuum dryer design performance, engineers need to balance the dual needs of a rapid drying time and high-quality end products. To achieve this, you can study the vacuum drying process with the COMSOL Multiphysics® software.
