Abstract: By using the method similar to the single-phase air flow around the single ball and on the base of finite volume,gas-liquid two-phase flow around single ball is numerically simulated,and compared with the single-phase air flow around the single ball.The results show that the addition of liquid can slow down the recover velocity on the central line and enhances the ball trailing vortex effect,and the magnitude of turbulence enhancement increases with the growth of the liquid void fraction.
