摘要
为了研究斜流对舵表面上脉动压力的影响,本文对斜流下的桨舵干扰过程进行了分析。采用大漩涡模拟方法开展数值模拟,使用滑移网格方法实现了螺旋桨的旋转。应用快速傅里叶变换方法对舵表面上的压力脉动开展频域分析,并对舵表面上脉动压力进行了沿展长方向、弦长方向和厚度方向的比较。结果表明:舵表面脉动压力的波动频率与螺旋桨叶频相关,近舵随边位置与舵的背流侧上的脉动压力与叶频的相关性较差,舵导边上的最大波动幅值出现在桨毂后方。本文研究为舵上的结构振动研究提供了研究基础。
The propeller-rudder interaction under oblique flow was investigated to determine the influence of oblique flow on the fluctuating pressure on the rudder surface.Simulations were carried out using the large-eddy simulation method,and the rotation of the propeller was realized by the slip mesh method.Frequency domain analysis of the fluctuating pressure on the rudder surface was realized by the fast Fourier transform method and then compared along the spanwise,chordwise,and thickness directions.Results show that the frequency of the fluctuation on the rudder surface is related to the blade frequency of the propeller.The fluctuating pressure on the position near the trailing edge and the back side of the rudder is poorly correlated with the blade frequency.The maximum fluctuation on the rudder leading edge appears in the area behind the hub.This research provides a basis for studies on rudder vibration.
