convection coeficient
(OP)
can anyone tell me if i can simulate heat transfer between air and steel , using one convection coeficient ?
i only discovered the gap conductance property with the clearance and conductivity and is not what i need .
thanks in advance

RE: convection coeficient
If you have an air gap then you need to consider convection in the gap and radiation between the two surfaces. For small gaps radiation will be dominant and you could neglect the convection to air. Refer to McAdams Heat Transfer or other such books.

RE: convection coeficient
and by the way , do you know how can i simulate this in Abaqus? because i´ve try to simulate the air as a solid, and then made the interaction between the surfaces, but i only find the gap conductance property and not the film property.
Thank´s
