Dear All
I am new to ANSYS and need some help [to simulate a heat transfer problem as below:
We have a housing filled by air and then a cap on the top of the housing prevents the air from escaping the housing. The cap and housing are in contact with each other, the housing transfers heat to the ambient gas by convection and the interior air has convection with both cap and the housing.
The question is here:
- How can I connect the faces of the housing and cap with a desired contact properties?
- How can I define the convection of the air trapped?

Please See the attachment
Thanks in advance
