WebFeb 8, 2024 · Rep Power: 34. E-C model in Fluent, either as a UDF or as a in-built function, has always been two-way, i.e., it models both evaporation and condensation. So, you need to hook only one mass-transfer mechanism. And it does not require any UDF, until and unless you want to apply saturation temperature as a function of saturation pressure. WebPlease note that the equation has been modified from its general form to be applicable to calculating evaporation from swimming pools.
