 September 13, 2013, 08:17 Heat transfer through a pipe located within the soil. #1 New Member   Rohit Tripathy Join Date: Apr 2013 Location: Vellore , India Posts: 6 Rep Power: 13 I have to simulate the heat transfer occuring as a result of forcing air through the pipe of an Earth air heat exchanger tube. The surrounding soil is to be assumed as a heat sink . What are the boundary conditions that i should use to correctly simulate this case ?

u can use velocity inlet for the air flow in the inlet side. i think so

Hi,

Have u able to sove your problem?.I have to solve the same kind of problem, but my heat exchanger is circulated with water. But, geometry would be the same. Can u tell me how you use boundary conditions?. Which solver u used for this.

Thanks
