 January 21, 2009, 08:18 conjugate heat transfer #1 amar Guest   Posts: n/a Dear I have two materials the first one is 0.5mm aluminum plate and on its top surface there is a 1mm frost. I have drawn the aluminum plate on the bottom of the computational domain and the frost on the top surface of the aluminum plate. There is a heat transfer between the air which flow through the domain from left to right and the aluminum plate through the frost. My problem is how to define the two materials and how to make fluent to calculate the heat transfer between the pale and the air through the frost. also do I have to mesh the aluminum and frost volumes? Note: the volume of aluminum plate is x=5,y=5,z=0.5 the volume of frost is x=5,y=5,z=0.5 the volume of the computational domain is x=10,y=5,z=5 I'm looking forward to your reply Yours Thanks a lot

May I knw what is the aim behind this CFD Modelling. regards uday
