I want do some works for heat pipe simulation during transit time, First I ‘ll construct a rod as heat pipe and then give the thermal conductive such as 10000W/m.K, I want to detect the cross section’s heat flux during the transit time ,if it great than some values I’ll change the rod’s thermal conductive. All the process can be done by icepak/fluent?
I know that maybe I can change the case file to use UDF for simulation but FLUENT's case format is not very clearly and has not official FLUENT case file format documentation.
Is there any people can give some suggestions? thanks a lot!
