Multi Fluid Total Energy
I want to simulate a multi fluid flow with air and CO2. Because I have to simulate it with "Total Energy", I need in CFX-Pre for die "Fluid Pair Models" the Heat Transfer Coefficient or the Nusselt Number. But I don't know how to calculate it for a mixture between two fluids.

Can anybody tell me, how can I calculate the heat transfer coefficient or the nusselt number? Thank you!
