How to Set Up a Mesh in COMSOL Multiphysics® for CFD Analyses
As a flow mechanics specialist preparing a mesh for CFD analysis, the geometry supplied by a CAD team is often exactly what you do not want. So, what do you do?
Happy Birthday, Henry Darcy
Henry Darcy was a civil engineer whose study of fluid dynamics led to the formulation of the equation now known as Darcy’s law. It also helped supply his small town in France with drinking water.
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.
How to Create Animations Along the Azimuthal Direction for 3D Models
Here’s a useful postprocessing trick for presenting your 3D modeling results: combine slice plots along the azimuthal direction in order to generate a nontrivial animation.
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.
Studying the Van Allen Belts with Particle Tracing Simulation
Get a closer view of the Van Allen belts, 2 donut-shaped belts of radiation that surround Earth, with the help of particle tracing software.
What Is the Doppler Effect?
A siren passes by and you hear a change in pitch. A bug swims across a puddle, causing ripples on the surface. A star in the sky has a reddish hue. These are all examples of the Doppler effect.
How to Model Conductors in Time-Varying Magnetic Fields
You can use the AC/DC Module to perform frequency-domain simulations for conductors in time-varying magnetic fields by describing the skin effect.
Analyzing the Current Distribution in a Lead-Acid Battery Design
The lead-acid battery in your car is not much different from the original one developed by Gaston Planté in 1859. 1 change is that you can now analyze the current distribution using simulation.
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.
