This method is considered to be accurate in identifying flow pattern oi gas-liquid two phase flow pipeline through example validation,which can be taken as a method to identify flow pattern in calculation of oil-gas mixing transportation process.

By using simulation-analysis software CFD(Computational Fluid Dynamics),STAR-CD,a three-dimensional simulation analysis was conducted of the semi-volute suction chamber of a gas-oil multiphase pump for flow fields at different void fractions.
