Hi guys,

I would like to know your opinion and advice on the following problem I have been working on lately.

I am studying the flow over an airfoil at a high Mach number. What I am trying to look into is how much heat I can dissipate when I impose a high temperature on a particular region of that airfoil. That is, I want to increase the wall temperature on that region only, and let the rest of the airfoil as is (adiabatic). I was thinking of using a UDF to define a temperature profile; however, while it is ok for the region where I have the increased temperature, I also need to define another value for the rest of the wall. This gives rise to the problem I have been having, which is that I do not know how to make sure that there is heat transfer only on the region I define the temperature on, while having zero heat transfer on the rest of the airfoil wall. In other words, I do not know whether it's possible to define a temperature on a region for an adiabatic wall boundary condition or not.

Modifying the mesh so that I can have one dedicated boundary for the temperature boundary condition and another for the adiabatic region is not an option, so I was hoping to know if there is a way to do this using an UDF.

Hope it makes sense. I would highly appreciate any suggestion.

Best regards
