基于STAR-CCM+的潜艇舵翼水动力性能研究
|
摘要
潜艇舵在设计的时候并未充分考虑潜艇伴流以及螺旋桨的影响,导致实际上舵的水动力效果与设计值存在偏差。为了解这种影响的大小,利用Star-CCM+分析棱柱层、湍流模型、网格离散、定常与非定常方法对敞水舵计算结果的影响,并选择较佳的物理模型对SUBOFF潜艇上的单独舵、直航打舵以及斜航工况进行计算,并将水动力计算结果与水池试验值和风洞试验值进行比较,分析艇体伴流对舵翼水动力的干扰,更深入认识艇体对舵的水动力影响,为优化潜艇舵翼设计提高潜艇操纵性以及降低噪声提供了参考依据。
The design of submarine rudder did not fully consider the influence of submarine wake and propeller, resulting in the fact that the hydrodynamic effect of the rudder deviated from the designed value. In order to understand the influence, Star-CCM+ was used to analyze the influence of prism layer, turbulence model, grid discretization, stationary and unsteady methods on the open rudder. And the best physical model was chosen for calculating the submarine SUBOFF Single rudder, direct rudder and pitchup working condition. The hydrodynamic calculation results were compared with the experimental values of the pool and the wind tunnel. The impact of the wake of the hull on the rudder wing was analyzed, the hydrodynamic influence of the hull on the rudder provides a reference for optimizing the design of the submarine's rudder wing to improve the maneuverability of the submarine and reduce the noise.
