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…
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.
Predicting Cavitation in Journal Bearings
When designing journal bearings for use in a rotating shaft, the effect of cavitation needs to be considered, because it can affect the performance of these components.
Dielectrophoretic Separation
Dielectrophoresis is a phenomenon in which an electric field is used to control the movement of electrically neutral particles. Learn about how to model this effect in both DC and AC fields.
Creating an App for Modeling Flow Control in a Pipe Network
Simulation apps can be used as dedicated tools for modeling the flow and pressure distribution inside a network of connected pipes. This would be useful in, for example, semiconductor processing.
