Diana Guest Posts: n/a	Hello all, I'm trying to model a U-shaped shell and tube heat exchanger with baffles and I want to find the pressure drop on the shell side, friction factor, and Nusselt number. The heat exchanger is very long so I think to take only a representative section from the middle. Starting from the long heat exchanger 3D CAD drawing, what is the appropriate procedure to follow to reach to the final meshing step. What e.g. is the flow proper flow domain and applicable boundary conditions? I'm quite confused! Thanks in advance, Diana
