Air cooling of heating plate

OpenFOAM 4.x

Case directory



Air flows in from the region "inlet" at a velocity of (0.1, 0, 0) m/s and a temperature of 300 K, and out from the region "outlet". In the middle of the flow path, there are two regions, "baffleFacesThermoBaffle1D" and "baffleFacesThermoBaffle3D", which play as heating plates and are cooled by the air flow. The model is calculated as a two-dimensional model with a single mesh in the Z direction.

Model geometry Model geometry

A thermal baffle model is used to model the heating plate. The upstream side plate is modeled with a 1D thermal baffle model (thickness 0.005 m, heat flux 100 W/m2) and the downstream side one is modeled with a 3D thermal baffle model.

The meshes are as follows, and the number of mesh is 2000.
