摘要
以19A导管配ka4-70、螺距比为1.0的螺旋桨为研究对象,通过求解RANS方程,采用CFD方法并借助STAR-CCM+流体软件,对其敞水性能进行了数值研究,与现有试验值进行了比较,从而探讨了不同网格类型和不同湍流模型对其敞水性能计算精度的影响。分析了特种推进器在进速系数为0.3时的黏性流场特性,验证了采用STAR-CCM+进行导管桨性能数值模拟方法的可靠性,为之后的导管桨黏性流场数值研究提供了参考意见。
The propeller with a 19A duct with ka4-70 and a pitch ratio of 1.0 is studied.By solving the RANS equation and using the CFD method and the STAR-CCM+fluid software,the open water performance is numerically studied.Compared with the existing experimental values,the effects of different grid types and different turbulence models on the calculation accuracy of the open water performance are discussed.The characteristics of the viscous flow field of the special propeller with a speed coefficient of 0.3 are analyzed.The reliability of the method of numerical simulation of the performance of the ducted paddle using STAR-CCM+is verified.It provides a reference for the subsequent study of the viscous flow field of the catheter paddle.
