You can define the interface aluminium and air easily. How come you were recommended star-cd for your type of study?

Assign cell type: Solid for the plate Fluid for the environment Then assign to the plate a wall boundary condition in which you enforce an heat flux (60 - 20)* 15 = 600 W/m^2 You can change the coefficient in a range of 0 - 15. That's all
