Dearest,
I have a problem with calculating a heat exchange coefficient to the wall in a very simple problem.
in practice study a 2d asymmetric problem: two fluids exchange heat in countercurrent separated by a wall of solid cells.
I tried to calculate it by changing the reference value and more or less the values return, but I would like to make a calculation more rigorous than this coefficient, assuming as t_ref the t of the fluid cell closer to the wall to get the local values of h_convective to mediate to get h_mean_wall.
do you have any idea for a custom-field-functions or do you have any other method that I ignore?
thanks and good work to all
