| 摘 要： | 基于均相流输运模型对NACA661-012型水翼进行了空化数值模拟,计算了不同空化数K和不同攻角α下的升力系数与阻力系数.从流场、压力场和边界层的变化分析了空化的产生发展对水翼升力和阻力的影响.当攻角α大于8°以后,空化流动的不稳定性增强,空泡呈现出周期性的生长溃灭,并伴有升力系数和阻力系数的周期性波动.计算结果与实验进行了对比,结果吻合较好.

| Abstract: | Homogeneous multi-phase transport equation based model was used to simulate the two-dimensional hydrofoil cavitation of NACA661-012.Lift coefficient and drag coefficient was computed as functions of angle of attack and cavitation number.The cavity oscillating cyclically can be observed with lift coefficient and drag coefficient changing cyclically when the angle of attack is greater than 8 degrees.Simulation results keep good accordance with the published experimental results. |
