Mesh independence studies

March 27, 2005, 05:34

Hello,

I am trying to model laminar flow forced convection through a single longitudinal fin. When I try to refine the mesh, I find that the change in the wall heat transfer coefficient first decreases till a certain mesh size and if I try to refine the mesh further, the difference increases by a large amount. I was wondering if anybody could guide me as to what mesh size I could use to ensure that the change is not much.

Many thanks, Akash
