An Introduction to the Physics of Rapid Detection Tests

April 20, 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

June 11, 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

February 24, 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

February 4, 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

November 19, 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.

Simulating Multiphase Flow in Porous Media with a Low Permeable Lens

December 13, 2018

Modeling phase transport helps you study the multiphase flow through a porous medium (such as groundwater through soil).

Predicting Solute Transport in Groundwater Using Simulation

January 18, 2018

In order for groundwater to be useful for irrigation and drinking, we need to understand how its various solutes move through the water. The Subsurface Flow Module includes features for this.

Computing Porosity and Permeability in Porous Media with a Submodel

September 27, 2017

Porous materials have complex geometries and may therefore be difficult to model. Setting up a microscale submodel is a useful approach to find the porosity and permeability of the medium.
