gas-liquid problem
 

Hi, Everyone, I am using CFX4.1 and solving gas-liquid mixing in a reactor. I want to solve the gas velocity based on liquid results( so I do not need to solve the gas velocity equations), However, I need to apply gas velocity results to calculate the gas volume fraction, so how can i avoid solving the gas velocity equations and which subroutine can I use to calculate the gas velocity and I can use these results to calcuate the gas volume fraction for the further iterations?

Thanks in advance. Tiger

CFX4.1 ?, that was an old one. Look at the physics, if the flow is separated or the same flowfield exist for both phases, then you can directly use the homogenous model, where only one flowfield is solved for both phases.
