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.
How to Compute the Acoustic Radiation Force
Did you know that objects can actually be moved by sound? This effect is called acoustic radiation, and it is an acoustophoretic phenomenon that can be analyzed in the COMSOL® software.
Using Perfectly Matched Layers and Scattering Boundary Conditions for Wave Electromagnetics Problems
Learn how to use scattering boundary conditions and perfectly matched layers to truncate domains for your wave electromagnetics problem — and which technique is best for your modeling scenario.
How to Perform a 3D Analysis of a Semiconductor Device
Open for a comprehensive introduction to performing 3D analyses of semiconductor devices in COMSOL Multiphysics®. We demonstrate with a bipolar transistor example.
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.
Cloaking Advancements for Flexural Waves in Elastic Plates
A European research group discovered a theoretical framework to both overcome the limitations of cloaking and achieve exact cloaking for flexural waves in Kirchhoff–Love plates. Get details >>
