Amphos 21: Modeling Coupled Thermo-Hydro-Mechanical-Chemical Phenomena
A guest blogger from Amphos 21, a COMSOL Certified Consultant, discusses the company’s iCP technology for modeling coupled thermo-hydro-mechanical-chemical phenomena.
Implementing a Simple Temperature Controller with a Component Coupling
Learn how to implement a simple temperature controller (a feedback loop) in a thermal process simulation in COMSOL Multiphysics®. We demonstrate with a silicon wafer example >>
Simulating Thermal Performance in Windows
Windows must be able to keep heat out during the summer and heat in during the winter in order to keep the inside of a building at a comfortable temperature, a process called thermal insulation.
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®.
Conjugate Heat Transfer
Get an introduction to the concept of conjugate heat transfer and see some of its applications and modeling considerations.
Predicting Microwave Drying of Potatoes
You may not think of reheating food in the microwave as a drying process, but as we saw at the COMSOL Conference 2013 Boston, microwave technology — the same technology used in domestic microwave ovens — can be used for drying fruits and vegetables. One poster presented at the conference featured microwave drying of potatoes and how the heat and mass transfer that occurs can be modeled to predict the drying process.
Thermal Modeling of Surfaces with Wavelength-Dependent Emissivity
Whenever we are solving a thermal problem where radiation is significant, we need to know the emissivities of all of our surfaces. Emissivity is a measure of the ability of a surface to emit energy by radiation, and it can depend strongly upon the wavelength of the radiation. This is very relevant for thermal problems where the temperature variation is large or when there is exposure to a high-temperature source of radiation such as the sun. In this post on […]
