For phase change I was assuming for each gram of vapor to liquid 2259J is released(is not it?!)

Did you mean 4.4e+7J/Kgmol? if we take 4.4e+07 J/Kgmol, then with 18.02g molar weight of water it would be 0.244e+07 J/Kg or 0.244e+4 J/g = 2440 J/g, so for 101 grams it release 0.246e+06J (close to what I was considering).

The residuals are attached for 100s and 600s. I am using mixture model with Lee evaporation/condensation, UDF written according to Antoine Equation for saturation pressure.
