摘要
采用CFD方法对吊舱推进器黏流水动力问题进行了数值研究.基于混合面方法,在均匀来流情况下,数值预报吊舱推进器定常水动力特性,获得其推力系数、转矩系数等水动力性能参数.以单桨拖式吊舱推进器为例,与试验结果对比,获得了很好的预报精度,能够为工程实际应用以及优化设计提供可靠的流动信息.
The viscous flow of pod propeller was simulated numerically. Based on the mixing plane method, the hydrodynamics characteristic of pod propeller with uniform inlet flow such as thrust coefficient and torque coefficient was obtained. The flow around single-propeller pulled type pod propulsion was simulated. Compared with the experiment results, the numerical results indicate good agreement. These detail flow information can be applied to engineering practice and optimization design.
