Volume fraction in multiphase simulation
I have been working on my thesis of master degree, It is related to multiphase fluid flow simulation, especifically in: gas-liquid vertical gravitational separator.
I´m working in ANSYS CFX and the most difficult part is to setup the volume fraction at the inlet.
The main goal of the thesis is to evaluate the separation process within the vessel, but the data used is from the real process, for example:
Oil rate, gas rate, pressure, densities, viscocity and so on..
THE VOLUMEN FRACTION DOES NOT APPEAR IN NO DATA SHEET.
How can I get this volume fraction?
please help me
if you have the oil rate, gas rate and densities you should be able to work out the total volume and also the volume fraction for each phase.
how do I get the volume fraction with that information?
Since the volume fraction is the volume of one constitutient divided by the the volume of all constitutient!!!
I just have mass flow rates and volume flow rate, I other word I just have FLOWS, and volume fraction is calculated by VOLUME.
