How to deduce how much water has turned into water vapor into fluent.

      Hi all.
      Evaporation calculation. Mixture: water and water vapoor.
      How to deduce how much water has turned into water vapor into fluent.
       
      In theory it goes like this:
      There is a variable responsible for the speed of the interfacial mass transfer process. It can be integrated over the volume and find out how much vapor is formed/absorbed in the entire volume per unit time.
      If you integrate the volume fraction of steam over the entire volume, you get the current volume of steam.
       
      How to do this in Fluent? Thank you.

      To calculate the mass of each phase at any given time, you can generate a volume integral report in Fluent. This report integrates the mass over the entire volume, allowing you to obtain the mass of vapor and liquid individually. I have attached a screenshot to clarify how to perform this task.
       
      Additionally, Fluent offers the option to select phase interaction quantities. This enables you to calculate other quantities, such as the mass transfer rate, at any time.
