This project consists of a conjugate heat transfer (CHT) simulation of a flow around a heat sink.
The requirement to perform a CHT simulation is that it should have different geometric solid volumes (3 in this case - 1 heat source, 1 heat sink and 1 fluid region). These 3 solid volumes should be non-overlapping, with the boundaries touching each other in order to setup an interface. The original CAD was provided by @ACH_Likey and the geometry is as shown below.
A multi-region mesh is generated. The following images show the mesh of fluid region and heat sink respectively.
Simulation and Post-processing
A constant temperature is given to the bottom surface of the heat source (power source boundary condition as input to the solid will be available soon with the SimScale platform) and a laminar steady-state simulation is carried out. The following images show the temperature contours across the cross-section of the fluid region and the solid domains.
