Hi all,

I have a problem of forced convection inside a pipe. Inside of the pipe flow a hot fluid and outside is constantly cold (cold water).

In the boundary conditions of the wall, must I determine the Convection? Or is it correct if you only determine the Temperature of the cold medium?

Thanks!

You need to provide the external temperature and the effective heat transfer coefficient up to the wall-inner fluid boundary. The wall-inner fluid heat transfer is calculated by Fluent.

Thanks Joe!

Is this effective heat transfer coefficient up to the wall-inner fluid so: Ae*U = 1/ (1/hAe + ln(re/ri)/2piLk) (A0 = external area)? Also must I turn on the option "Shell conduction" and need I to provide the wall-thickness?

Thanks very much.
