Seeing Through Solids: Discovery and Applications of Photoacoustics
The field of photoacoustics started with Alexander Graham Bell and some sunlight. Now, photoacoustic imaging is used for nearly anything involving generating images of opaque material samples.
Describing Viscoelastic Behavior with an Oldroyd-B Benchmark
The Oldroyd-B model is used to define viscoelastic behavior in fluids such as clay, toothpaste, and oil. We present a benchmark model for a fluid with viscoelastic behavior under strain.
The Nonparaxial Gaussian Beam Formula for Simulating Wave Optics
Here’s your introduction to the nonparaxial gaussian beam formula, which is used for simulating wave optics problems in COMSOL Multiphysics®.
Analyzing a Centrifugal Pump Design with Frozen Rotor Approximation
Mechanical engineers can analyze the design of centrifugal pumps using the Frozen Rotor Approximation, which is available in the Mixer Module, an add-on to the CFD Module.
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.
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.
