Modeling Droplet Flow in an Open Space with COMSOL Multiphysics®
If you are jogging six feet apart from someone else, should you both be wearing masks? Simulation was used to analyze the motion of particles between two runners in an open space to find answers.
How Does This Lip Gloss Appear to Defy Gravity?
We attempt to explain a mysterious, gravity-defying phenomenon involving a viral video, dielectric materials, electrostatics, and lip gloss.
Optimizing an NIV Mask Design with Multiphysics Simulation
NIV masks offer a form of noninvasive monitoring and ventilation for COVID-19 patients, which lessens the need for ventilators and other mechanical respirators.
6 Ways Engineers Are Using Simulation to Help the Environment
Energy-efficient buildings and appliances. Safe nuclear waste storage. Well-preserved freshwater lakes. These are just a few examples of how simulation is being used to help the environment.
Modeling and Simulation of Multiphase Flow in COMSOL®: Part 1
Multiphase flow can be modeled on scales ranging from fractions of microns to tens of meters. Get an overview of the dispersed and separated multiphase flow models for different types of flow.
Thermal Equilibrium and Nonequilibrium Heat Transfer in Porous Media
Heat transfer in porous media can occur under thermal equilibrium, such as a rock consisting of different minerals or trapped fluids, or nonequilibrium, like a thermal energy storage (TES) unit.
Modeling Darcian and Non-Darcian Flow in Porous Media
Get an introduction to the theory behind modeling flow in porous media, including the Kozeny–Carman, Forchheimer, Ergun, Burke–Plummer, and Navier–Stokes equations.
How to Simulate Control Systems Using the PID Controller Add-In
A PID controller can be used in a variety of industries. This blog post demonstrates how a PID controller add-in can be easily incorporated in two simulation examples.
