摘要/Abstract

摘要： 基于OpenFOAM软件平台,采用改进的延迟分离涡模拟（IDDES）模型,结合滑移网格方法,对一组对转桨和对转舵桨的水动力性能进行数值预报,并利用快速傅里叶变换（FFT）对推力系数进行频谱分析。对转桨数值计算结果与模型试验结果比较,推力、扭矩系数以及推进器效率的误差分别在3%、2%和5%左右,验证了该数值方法的可行性。对转舵桨数值计算结果提示：压差阻力是吊舱和立柱阻力的主要成分,在立柱的前端存在回流,对立柱的优化设计可以从这两方面入手;立柱和吊舱的存在能够减小轴承力导致的振动。

Abstract: The hydrodynamic performances of a contra-rotating propeller and a contra-rotating rudder propeller are predicted by using the improved delay detached-eddy simulation (IDDES) model and sliding mesh method based on the OpenFOAM software. The thrust coefficients are analyzed by the fast Fourier transform (FFT) method. The numerically calculated thrust coefficients, torque coefficients and propulsion efficiencies of the contra-rotating propeller are compared with the model test results with the errors of 3%, 2% and 5%, respectively, indicating the validity of the numerical method. The numerical results of the contra-rotating rudder propeller show that the pressure drag is the main component of the drag of the pod and strut, and there is a reverse flow at the front of the strut. The strut, therefore, can be optimized from the two aspects. The strut and the pod can also reduce the vibration caused by the bearing force.

Key words: improved delay detached-eddy simulation(IDDES), contra-rotating rudder propeller, spectrum analysis, interference
