摘要
针对锥形空化器的背流面空化情况及空化器锥角对于空化器的流体动力的影响问题，基于流体仿真软件Fluent进行数值仿真计算，得到不同锥角下的空泡长度，与渐进解公式进行对比，验证仿真的准确性，分析锥形空化器阻力系数和升力系数随空化器攻角和锥角的变化规律，结果表明，锥角小的空化器背流面进入空化状态时的攻角也小。
In order to analyze the cavitation of the backilow surface of the conical eavitator, the effect of the cone angle of the cavitator on the hydrodynamic force of the cavitator was simulated numerically by Fluent. The accuracy of the simulation was verified by comparing the length and the progressive solution formula. The variation law of the drag coefficient and the lift coefficient of the cone-shaped eavitator with the cavitation angle and cone angle were analyzed. The results showed that the angle of attack of the cavitator with small cone angle is also small.
