Dear Collegues,
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
