 June 16, 2011, 17:35 Help needed in using wall BC for heat transfer analysis of heat exchanger tubes #1 New Member   Hassaan Rafi Join Date: Jun 2011 Posts: 7 Rep Power: 6 Hello! I am using ANSYS Fluid Flow Fluent 12.0 to solve this case and I am new to CFD analysis. I cant seem to figure out how to use wall BC to simulate heat transfer between two fluids. I am analyzing the heat transfer between two fluids separated by a metal pipe. I am using the wall boundary condition to separate the fluids. However, i am unable to understand how to use the wall BC. I especially need to calculate the wall heat flux involved :S Can anyone help me with this? any examples or tutorials that can be of help? Thanks in advance!
