Help!!!!!!heat transfer over annular fin

July 19, 2000, 13:02

First, sorry , I don't writting english good. I need information about how have the heat transfer over a annular fin, the boundary conditions are: solid for the annular fin, wall for the superficial of tube, and the boundary external, the environment, is the wall. My problem is: the Fluent create in the fin a : WALL AND WALL SHADOW, and for default are adiabatic, and the heat of transfer don't happen!!!

HELP IS URGENT!!!!!!!

check fluent user's manual for wall-boundaries: the wall and wall shadow allows you to specify different heat transfer parameters for the two sides of the wall. You need to change the default
