Thank you for your reply.

I have some concerns about configuring the evaporation and condensation conditions in Fluent. Here is the specific scenario I intend to simulate:

Initially, the air (dry air+ water vapour) entering the tank has a temperature of 25°C and a relative humidity of 50%. Additionally, liquid water is also introduced into the tank at the same temperature.

To create a conducive environment for condensation, the temperature of the bottom wall should be set below the dew point temperature, which is assumed to be 10°C. With an air temperature of 25°C and 50% RH, the calculated dew point temperature is 14.5°C.

My objective is to observe condensation phenomena under these prescribed conditions. I kindly request your guidance on how to establish these parameters effectively within Fluent. Any suggestions or available options for this simulation would be highly appreciated.

Regarding the materials properties tab, I am uncertain whether I should modify the standard state enthalpy and reference temperature for both water in the liquid phase and water vapor. I would appreciate your advice on this matter as well.
