To read about more updates to the Heat Transfer Module, check out the 4.3 Release Highlights page. A wall condition can be defined between two fluid domains with the Interior Wall boundary condition, which is available in the Conjugate Heat Transfer and Nonisothermal Flow interfaces. So long, dense meshes! Thin walls can now be represented as interior boundaries instead of having to define a solid domain with a wall boundary condition on both sides. This is great news for those involved in heat transfer projects. Additionally, radiative heat transfer between thin structures is now possible when surface-to-surface radiation is used together with the Thin Conductive Shell user interface. The refractive index parameter has also been implemented to enable modeling of radiation through glass, water, and other media with a refractive index different than 1.0. (The solar position is only based on the position on Earth, not any other planet or the moon, but it is fine for airplanes and might work for a satellite orbiting close to Earth).ĭefining an external radiation source using the Solar Position option. You can easily define the direction and intensity of the sun’s incident radiation based on the latitude and longitude position on Earth, the date, and the time with this new option.
COMSOL 5.1 RADIATIVE HEAT TRANSFER SOFTWARE
To use the words of Nicolas Huc, project leader for the Heat Transfer Module development at COMSOL in France: “it makes a huge difference if you forget to take the sun’s radiation into account.”Īs of version 4.3 of the COMSOL Multiphysics® software and add-on Heat Transfer Module, external radiation sources can be defined in 3D for all physics user interfaces via the Solar Position option. Heat transfer also plays a vital role in designing outdoor devices in terms of maintaining temperatures in extreme hot or cold environments.

Knowing the sun’s radiation and thermal effects is very important to designers within the building industry, especially in designing “green” buildings.
