Hello everyone,
I have to set up the temperature boundary conditions for a hot liquid flowing into a non-insulant pipe.
Let T* be the temperature at the inner surface of the pipe and T0 the temperature at the outer one. A good boundary condition may be constantGradient with value (T*-T0) / k, where k is the pipe thermal conductivity (Fourier formula).

Well, since T* is supposed to wary from point to point, is it possible to define such a boundary condition? If possible, how?

Thank you in advance
