Consider the interface at the start of the simulation (see attached image): at one side we have only moist air in the cell, at the other side we have only water-liquid in the cell. Using the analogy above and assuming atmospheric pressure, the absolute pressure in the cell with water liquid is approximately 101.3 kPa. This puts the saturation temperature at 100C. That means the water temperature has to get to 100C for evaporation to take place. This is the problem I'm experiencing. nThe saturation temperature seems right in the moist air since I am using partial pressure to calculate, however, it stays at 100C every time in the liquid and no evaporation occurs. n
