Heat Transfer: Energy Imbalance with a Centrifugal Blower

Issue:

A heat transfer simulation contains a centrifugal blower material. The heat transfer results either do not agree with known results or there is an energy imbalance.

Solution:

Solution

Modify the geometry so that the back wall of the blower part (the surface with no flow) contacts a solid surface. This ensures that the surface is adiabatic, and does not compromise the heat transfer solution by erroneously losing heat.
