Hi, 

Thanks for helping. The wall boundary condition I used is adiabatic wall, so I cannot use HTC = (wall temp - wall adj temp) / (-k * dT/dn). I need to get the HTC wihch is calculated based on wall function (see the attached figure).

I am dealing with the simulation of ice accretion now, in which case there is a thin water film on the solid surface. I assume the HTC between air and water film is equal to that between air and solid wall. And I need to use the HTC between air and water film to calculate the mass of froozen water.
