Hi All,

I am working on the evaporation-condensation of cryogenic hydrogen. I had been trying with in-built Lee model but it is not giving the required output, especially the temperature or thermal stratification.

I went through some research articles on CFD modeling vapor-liquid phase change and observed that people have used Schrage model.

I want help in writing UDF for Schrage model which will provide the mass flux and should be multiplied with area density to give the overall mass in terms of kg/m^3-s. I am attaching the snap for your reference. Please help me through this.
