摘要
为了探讨吊舱推进器瞬时回转工况中的水动力性能,本文使用RANS方法,采用了SST k-ω湍流模型对吊舱推进器所受载荷进行研究。螺旋桨模型选用右旋四叶桨,计算域使用切割体网格生成器对网格进行划分。吊舱推进器的运动采用了滑移网格的方法实现连续摆动;探讨了不同进速系数下的螺旋桨载荷特性,并且比较了吊舱推进器在瞬时回转工况中和稳定斜流工况下的水动力性能。数值模拟结果表明:与稳定斜流工况下相比,吊舱推进器在从左舷转向右舷的过程中推力系数更大。随着斜流角的增加,瞬时工况和稳定工况中下吊舱推进器所受载荷变化趋势一致。
In order to study the hydrodynamic performance of a pod propeller under azimuthing conditions,we adopt the RANS method and the SST k-ωturbulence model to study the loading of a pod propeller.A right-handed four-blade model propeller is used as the target,the cut cell mesh is used for the gridding of the computational domain,and a sliding mesh technique is used for simulating continuous flapping of the pod propeller.We investigated the loading characteristics at different advance coefficients and compared the hydrodynamic performance under azimuthing conditions with that under steady oblique inflow.The numerical results show that the thrust coefficient is larger than that in steady oblique flow as the pod propeller flaps from left to right board.With an increasing oblique angle,the loading variations at transient and steady conditions become increasingly similar.
