摘 要:为了研究新型扭曲舵对潜艇水动力性能及艉流场特性的影响,本文采用SST k-ω湍流模型结合全域结构网格分别对带扭曲舵和常规舵的SUBOFF潜艇模型进行模拟计算,对比并分析常规舵潜艇和扭曲舵潜艇在自航状态下的推进性能、螺旋桨叶片压力分布和艉流场速度分布。结果表明:相对于常规舵潜艇,扭曲舵潜艇达到自航状态时螺旋桨所需的转速降低,桨叶吸力面压力最小值提高,艉流场中的周向速度显著降低,螺旋桨的推进效率提高了约7.67%,且扭曲舵并不会对潜艇阻力产生太大影响,为提高潜艇推进性能提供了新的途径。The SST k-ω turbulence model combined with the whole-domain structured grid was used to study the influence of a new type of twisted rudders on the hydrodynamic performance and wake field characteristics of a submarine.Simulations were conducted on SUBOFF submarine models with twisted and conventional rudders.The propulsion performance,pressure distribution of propeller blades,and velocity distribution of the wake field between the submarine with conventional and twisted rudders in a self-propulsion state were compared and analyzed.Calculation results showed that the rotation speed required for the submarine with twisted rudders to reach the self-propulsion state was reduced.The minimum pressure on the suction surface of the blade increased,the circumferential velocity in the wake field significantly reduced,and the propulsion efficiency was improved by approximately 7.67%.The twisted rudder had little effect on the resistance of the submarine.This research provides a new way to improve the propulsion performance of submarines.
