hello all,
i am a bit new to CFD, so plz forgive my basic question.

i want to determine change in wall temperature and wall heat flux for 2d axissymmetric case,

can any one guide me on the boundary conditions i should use.

i am using air ideal gas and i have modelled wall as fix temperature and default heat flux zero conditions both times i am getting wrong results.

can anyone plz guide,as i am really stuck badly

thank you.

if you could post a picture or more details about the module/ software you're employing and a sketch of what you're trying to do, that would help..
