Hydrodynamic features of underwater vehicles based on flow control

  • 摘要: 利用CFX对水下航行体流体动力特性进行了数值模拟研究.求解了混合介质的剪切压力输运湍流模型控制方程、雷诺-平均奈维尔-斯托克斯方程以及各相间的质量输运方程,采用三维数值模拟方法对比分析了不同流动控制方案的水下航行体空泡形态特征、表面压力分布和阻力系数变化特性,讨论了不同参数对减阻效果的影响.结果表明,对于有横流作用的水下垂直发射航行体,多相流动控制不仅可以降低通气空泡的不对称性和航行体阻力,同时可以均匀迎流面和背流面压力,从而实现航行体多相流空泡形态及表面压力特性等的控制.此外,通气口的位置对减阻效果具有显著影响.
