Does It Matter Which Ball the FIFA World Cup™ Teams Practiced With?
In an attempt to determine what type of soccer ball is best to prepare for the FIFA World Cup™, we set up a backyard experiment involving a leaf blower, level, and a few soccer balls.

Optimizing Combustion Particle Control in an Electric Filter Design
To optimize the design of an electrostatic filter, researchers from Switzerland used multiphysics modeling, validating their results by comparing them to experimental data.

Terminal Velocity, Drag Coefficients, and FIFA World Cup™ Predictions
Is it possible to predict the winners of the FIFA World Cup™? We forgo consulting a psychic and instead analyze the terminal velocity and drag coefficients of different balls with CFD simulation.

Modeling Free Surfaces in COMSOL Multiphysics® with Moving Mesh
You can model free liquid surfaces that do not undergo topology changes using moving mesh functionality in the COMSOL® software. Here’s a thorough guide on how to do so.

Analyzing Multiphase Flow in an Airlift Loop Reactor Benchmark Model
This blog post features a benchmark model of an airlift loop reactor that validates the use of CFD simulation for analyzing multiphase flow.

Two Methods for Modeling Free Surfaces in COMSOL Multiphysics®
We take you through 2 methods for modeling free surfaces in the COMSOL® software: the level set and phase field methods. Learn how to use each method and their benefits.

How to Solve a Classic CFD Benchmark: The Lid-Driven Cavity Problem
We demonstrate how to solve a classic benchmark problem in the field of computational fluid dynamics, the lid-driven cavity problem, using the COMSOL® software.

Modeling Fluid-Structure Interaction in a Heart Valve
The average human heart beats 100,000 times per day, but what if the person has cardiac issues? Modeling fluid-structure interaction in a heart valve can help researchers develop new treatments.
