custom Interfacial Area Density (Thermal Phase Change)
I am using the Thermal Phase Change model in ANSYS CFX to model evaporation in an adiabatic pipe, evaporation due to pressure loss. At the inlet of the pipe there is just liquid and at the outlet I have 0.95 Volume Fraction vapor.
I don't like the linear clipping above the maximum Interfacial Area Density (Standard 0.8 Volume Fraction). Is it possible to use a custom Interfacial Area Density or somehow override the linear clipping?
Thank you very much!
I found a way around the linear clipping.
Add in the CCL of the Domain "Maximum Volume Fraction for Area Density = 1.0". It will shut down the clipping. Now you can model your Interfacial Area Density completely via the Mean Diameter of the disperse Phase.
I hope this information will be useful to someone in the future.
