摘　　要：根据汽蚀管结构,采用FLUENT软件进行了汽蚀管流场数值模拟,比较了不同结构尺寸对流量的影响。结果表明:汽蚀管入口倒角对流量控制有较大影响,不倒角时流量明显减小。Based on venturi configuration, venturi inner flow field was simulated with FLUENT software. The influence of different configuration size on flow rate was compared. The results indicate that the inlet chamfer of venturi plays an important role in flow rate control and flow rate will de- crease obviously without inlet chamfer.
