摘要
文章采用求解RANS方程的方法,结合VOF方法和RNGk-ε湍流模型,对二维超空泡剖面入水问题进行了数值模拟,主要研究了不同"杯"形随边剖面入水时对流场的影响,计算结果清晰地展现了自由表面的演变过程及喷溅现象。可为半浸桨的优化设计作理论指导。
The entry water of 2D suppercavitating hydrofoil section was numerically simulated by solving RANS equations with RNG k-ε turbulence model and VOF (Volume of fluid) method. The effect on flow filed of different cupped section was mainly investigated,The calculated results clearly show the splash and evolvement of entrying free surface.It is useful for designers to design the optimum semi-submerged propeller.
