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. WebBy default, Ansys Fluent uses the diffusion-controlled model for the vaporization/boiling model. We don’t get into more details in this article, but it would be better to use a convection/diffusion-controlled model when high evaporation rates. For slowly evaporating droplets, both models are expected to give similar results. It is available ...
