Hello CFD enthusiasts,

I have an observation rather than question. Please correct me if I am worng. If I apply one of the following conditions at a WALL type surface
1. Heat flux at wall
2. Adiabatic wall
3. Constant wall temperature

The heat flux would be
1. same as given
2. zero
3. some value depending on flow above.
Is this my concept correct? One of my friend wants heat flux at wall while I said that i can give only temperature due to second BC (i.e adiabatic wall) condition has been applied.

Thanks and regards,

SJ

1. Yes. 2. Yes. 3. Yes.


That said, if your friend wants to apply a heat flux, why are you doing 2, insisting that only 3 can be done (even though you are doing 2), and not doing 1?

Thanks, Lucky, I think you did not get my last point. I said that when friend asked me to give heat flux, I refused because I said I cant give you heat flux since the wall is adiabatic. I can only show you temperature at the wall.
