摘　　要：应用Fluent流场模拟软件对轴流式油气混输泵在不同的动叶片重叠系数和不同含气率下进行流场模拟,得出其动叶、静叶压力场及速度分布,进而得到不同工况下整机效率及扬程曲线。动叶片重叠系数大于1的整机效率明显高于动叶片重叠系数等于1的整机效率。为了提高整机性能,应选择动叶片重叠系数大于1。Using Fluent（computational fluid dynamics） software,the pressure field and velocity distribution of moving and static blade are derived by flow field simulation at overlapping coefficient of different moving blade and different air voids,and the overall efficiency curve are shown at different working condition.The results show that：the overall efficiency of pump is higher than the coefficient of equal to 1,when the overlapping coefficient of moving blade is greater than 1.Therefore,the overall efficiency of the pump is improved by using the overlapping coefficient is greater than 1.
