Tube bundle simulation using porous media

Jitendra

Hi everybody,

I am simulating a flow through tube bundle (inside heat exchanger) and I want to simulate the bundle using porous media (or equivalent source terms) Now from some coorelations (grimsons charts) I have got the pressure drop - velocity relation for my case. Now the problem is how to define the source term so as to take care of bundle as resistance.

Any help is highly appreciated.
