Modeling the Permeability of Composite Reinforcement Materials

11. Nov 2021

Here, we go over how to model the permeability constant of an idealized composite reinforcement material.

Fully Coupled Hydromechanical Modeling of Fractured Media

1. Jul 2021

Dr. Qinghua Lei of ETH Zürich demonstrates a novel method for modeling fully coupled hydromechanical processes in fractured media with 2 examples: fluid injection and underground excavation.

Modeling a Rapid Detection Test in COMSOL Multiphysics®

21. Apr 2021

Curious about how exactly the rapid detection tests for COVID-19 work? Get a comprehensive explanation here, as well as 3 example models in COMSOL Multiphysics®. (Part 2 of 2)

An Introduction to the Physics of Rapid Detection Tests

20. Apr 2021

Rapid detection tests based on lateral flow assay (LFA), also called immunochromatographic tests, can be thought of as quite advanced, yet very robust, microlaboratories. (Part 1 of 2)

Introducing the Porous Media Flow Module

11. Jun 2020

From multiphase transport and non-Darcian flow to local thermal equilibrium and nonequilibrium, we discuss the advanced porous media flow modeling you can do with the Porous Media Flow Module.

Modeling Darcian and Non-Darcian Flow in Porous Media

24. Feb 2020

Get an introduction to the theory behind modeling flow in porous media, including the Kozeny–Carman, Forchheimer, Ergun, Burke–Plummer, and Navier–Stokes equations.

Analyzing the Impact of a Melting Frozen Inclusion

4. Feb 2020

One example of the effects of climate change is the melting of permafrost in northern boreal regions. In this blog post, we show an example of a melting frozen inclusion in a porous medium.

Integration of Geological Structures into Regional-Scale Groundwater Models

19. Nov 2019

To study the dynamics of hydraulic processes at different scales, geotechnical researchers need to be able to integrate complex geological structures into their hydrogeological models.
