Modeling a Displacement Ventilation System
There are 2 different types of ventilation systems: mixing ventilation and displacement ventilation. Displacement ventilation is mainly found in offices, schools, and other public spaces.
Multiphysics Analysis of Advanced Materials: Ceramic Matrix Composites
A guest blogger from AltaSim Technologies discusses ceramic matrix composites and how to accurately analyze the production of such an advanced material.
Modeling PSU Cooling with COMSOL
A forced convection cooling system, such as a PSU, is used for removing excess heat produced by electrical computer components. You can model this device in COMSOL Multiphysics®.
Differentially Pumped Vacuum Systems for Spectroscopic Imaging
X-ray photoelectron spectroscopy is an imaging technique used extensively in R&D to characterize the chemical and electronic properties at the surface of a material. Learn about this technique.
Conjugate Heat Transfer
Get an introduction to the concept of conjugate heat transfer and see some of its applications and modeling considerations.
Red Blood Cell Separation from a Flow Channel
Lab-on-a-chip technology can be used to separate red blood cell via magnetophoresis — for example, motion induced by magnetic fields. Simulation can be used to optimize such devices.
Optimizing Dialyzer Design Using Multiphysics Simulation
A while back, I had the opportunity to speak with Steven Conrad, a critical care physician at the Louisiana State University (LSU) Health Science Center in New Orleans. Not only is Dr. Conrad a physician as well as a professor at LSU, he’s also a biomedical engineer who uses finite element analysis (FEA) to conduct research on the design of dialyzers. Dr. Conrad uses COMSOL Multiphysics to gain a deeper understanding of the physics behind these devices, and to create […]
Simulating Viscous Fingering Using Equation-Based Modeling
A prospective user of COMSOL approached me about modeling viscous fingering, which is an effect seen in porous media flow. He hadn’t found a satisfying solution elsewhere, so he turned to COMSOL. I’d like to share with you some of my insight on how to go from idea to model to simulation by taking a “do-it-yourself approach” and utilizing the equation-based modeling capabilities of COMSOL Multiphysics.
