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…
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.
Visualizing Fluid Flow with Streamline Plots
As part of our blog series on postprocessing, we demonstrate the use of streamlines to visually describe fluid flow in your simulations. Learn how with an example of flow through a pipe elbow.
Hydrocooling Analysis for Fresh Produce Safety
During the hydrocooling process for tomatoes, bacteria can seep through and contaminate the food, making it unsafe to ingest. Researchers from Cornell University used simulation to investigate.
Improving the Beer Brewing Process with Simulation
Which side of home beer brewing are you more interested in: The culinary side, like the recipes and ingredients, or the engineering one, like the conjugate heat transfer and chemical reactions?
Optimizing the Continuous Casting Process with Simulation
To optimize the steelmaking process of continuous casting, researchers at SMS Concast turned to simulation. One result? A steelmaking plant in Taiwan reduced yearly CO2 emissions by ~40,000 tons.
Acoustic Levitation Puts a Pure Spin on Medicine Fabrication
Engineers from Argonne National Laboratory used multiphysics simulation and trial-and-error prototyping to optimize the effectiveness of an acoustic levitator for medical fabrication.
Converting the High Flux Isotope Reactor to LEU Fuel
Learn about an initiative that requires nuclear research reactors currently using highly enriched uranium fuel to be converted to low enriched uranium fuel — and how simulation can help.
