joshkellyjak is on a distinguished road

Is it possible to set a constant Prandtl number alongside the Sutherland transport model? From my results so far it appears Pr=1 (approx) but I want Pr = 0.71 throughout the flow, how do I do this? I am using the rhoCentralFoam and my test case is supersonic flow over a flat plate.

Thanks in advance

Most probably not.

When you select Sutherland for the transport model, you specify how OpenFOAM calculates the dynamic viscosity and the thermal conductivity.
This leaves you with no remaining independent quantities. Hence, the Prandtl number is already fixed.

The screenshots attached to this post, were taken from my "manual", which can be found here
