OpenFOAM® tutorial : Fan and Fins - Conjugate heat transfert

preview_player
Показать описание
This tutorial shows how to set up a numerical model with conjugated heat transfer using the chtMultiRegionFoam solver. The case configuration is a fan cooling a finned radiator mounted on a heat dissipating component. The fan is modeled through specific boundary conditions simulating a zero-thickness actuator disk. The tutorial uses many advanced features of OpenFOAM® to efficiently simulate industrial heat transfer applications:

chhtMultiRegionFoam with 3 domains (1 fluid and 2 solids), transient and turbulent flow, perfect gas.
snappyHexMesh in multi-regions framework with boundary layer insertion.
fan modeling (pressure and tangential velocity jump) using performance curve p = f (U).
source term for heat generation in a solid element.

CFD-training does not give any warranty to the numerical results obtained within this tutorial due to the absence of verification or validation.

Did you add some sort of swirl to the fanflow?

Hi, did you define fans as momentum sources?
