How do I obtain Void fraction from FLUENT Multiphase CFD Simulation?
 

Hello,

Please how can I obtain Void fraction (i.e. fraction of gas in the gas-liquid mixture) from FLUENT Multiphase CFD Simulation. What do I need to specify to obtain it? I specified the Input Parameters/physical properties of Air & Liquid, the pipe dimensions, and the Gas Superficial Velocities for different runs but noticed only one of them was used in the simulation.

I used Volume of Fluid (VOF).

Please kindly help with this. Thank you.
