Modeling Laser-Material Interactions with the Beer-Lambert Law
Did you know that you can use the Beer–Lambert law to model laser–material interactions in COMSOL Multiphysics®? Learn how here.
How Can I Build an Efficient Stirling Heat Pump?
Did you know that heat pumps are also called Stirling engines? These systems can operate on incredibly low temperature differences — some only need human body heat to work!
Using the Boussinesq Approximation for Natural Convection
Today, we compare the Boussinesq approximation to the full Navier-Stokes equations for a natural convection problem. We also show you how to implement the Boussinesq approximation in COMSOL Multiphysics software and discuss potential benefits of doing so.
Studying the Airflow Over a Car Using an Ahmed Body
The Ahmed body is a benchmark model widely used in the automotive industry for validating simulation tools. We discuss simulating airflow over an Ahmed body to optimize automotive aerodynamics.
An Analysis of Syngas Combustion in a Round-Jet Burner
By combining the Reacting Flow interface and the Heat Transfer in Solids interface, we can study the syngas combustion in a round-jet burner. Get details…
Can We Hear the Shape of a Drum?
Over half a century ago, Mark Kac gave an interesting lecture on a question that he had heard from Professor Bochner ten years earlier: “Can one hear the shape of a drum?”
Simulating the Insertion of a Snap Hook
Snap hooks, a type of fastener that involves the insertion of a hook into a slot, are found in the automotive industry. Simulation can be used to analyze their insertion and removal.
Instability in Portable Washing Machines
A varied distribution of clothing can cause walking instability in both traditional and portable washing machines. Multibody dynamics analysis can be used to avoid this effect in machine designs.
Improving Your Meshing with Partitioning
It can be tedious to subdivide your CAD geometry into a finite element mesh. In this blog post, we demonstrate how to use a manual meshing method called geometric partitioning to do so.
Vivaldi Antenna Design Analysis
Did you know the Vivaldi antenna was invented by someone named Peter Gibson? As the story goes, he had a passion for music and chose to name the antenna after Antonio Vivaldi, a Baroque composer.
Tears of Wine and the Marangoni Effect
Have you ever noticed that when drinking a glass of wine, sometimes “tears” fall down in the inside of the wine glass? This is the Marangoni effect in action! Learn more and see examples…
Simulating Injection Mold Cooling
Injection molding is the most common form of polymer manufacturing because large amounts of products can be produced quickly. By simulating this process, we can avoid defects in these products.
