摘　　要：作为特种船舶高速推进装置的大侧斜螺旋桨,凭借其侧斜角较大的特殊结构导致由螺旋桨引起的轴承力和表面力特性减小,这对于提升推进器的推进性能以及效率性能有着重大意义。采用基于RANS方程的CFD数值模拟方法,对某五叶大侧斜螺旋桨(侧斜角度为55°)进行水动力学仿真并与水池试验结果对比,结果显示仿真结果具备可靠性与精确性。以大侧斜螺旋桨的侧斜分布为变量,并以原型桨为基础且只改变其侧斜分布而建立3个大侧斜螺旋桨模型,侧斜角度分别为40°、50°和60°。然后,对3个不同侧斜角度的大侧斜螺旋桨进行了定常敞水特性水动力学仿真实验。实验结果表明,随着螺旋桨侧斜角度的增大,螺旋桨的推进性能和高效性能都有所提升。As a special high-speed propulsion device for ships,leads to the reduction of bearing force and surface force characteristics caused by propeller,which is of great significance for improving the propeller’s propulsion performance and efficiency performance.Using the CFD numerical simulation method based on the RANS equation,the hydrodynamic simulation of a five-blade high skew propeller(with a skew angle of 55 degrees)was carried out,and the results were compared with the pool test results.The results show that the simulation results are reliable and accurate.Based on the prototype propeller and only changing its skew distribution,three high skew propeller models are established with the skew distribution of the high skew propeller as the variable.The skew angles are 40,50 and 60 respectively.Then,the hydrodynamic simulation experiments of steady open water characteristics of three high skew propellers with different skewed angles are carried out.The experimental results show that the propeller’s propulsion performance and efficiency are improved with the increase of the propeller’s skew angle.
