Heat transfer BC with two materials

January 25, 2005, 03:26

I am trying to study heat transfer between two materials.One is a liquid and other is solid.How convective heat transfer can be specified on the interface wall.

You shouldn't have to specify anything - if you have the energy equation turned on, heat will transfer(other than specifying type WALL).

I have walls outside my air flow that have a temperature, and they transfer heat into the air.

If you are trying this with natural convection only, and convection doesn't occur, you might not have gravity effects turned on. This would fail to create buoyancy and drive the convection.

I'm pretty new at this - somebody correct me if I am wrong!
