摘要
[目的]尾板设计一般追求高速减阻,对于同时以巡航和设计航速为优化目标的水面舰船尾板设计,其航速覆盖范围广,需重点对尾板参数的选取予以研究。[方法]采用计及航行姿态的粘性兴波流场数值模拟与模型试验验证相结合的设计方法,开展尾板多工况参数化优化设计。通过多方案数值仿真与阻力、自航模型试验的对比分析,总结得出尾板长度和下反角对于排水型水面舰船巡航和设计航速减阻节能的影响规律,并对CFD数值模拟结果的有效性进行初步的分析验证。[结果]结果表明,通过对尾板参数的优化,巡航航速约可节能3%,设计航速约可节能5%,达到了巡航和最大航速同时实现减阻节能的设计目标。[结论]所做研究可为后续排水型水面舰船尾板参数的优化设计提供理论支撑。
[Objectives]The design of stern flap usually focuses on resistance reduction at high speed.For surface warship stern flap design which is aimed at optimizing the cruise speed and design speed,the cruise speed comes in a large range,so the parameter selection of stern flap needs to be emphasized.[Methods]The design method combining viscous wave making flow field numerical simulation and model test verification,which take into account the navigation attitude,is used for optimization of stern flap with multiple condition parameters. Through comparative analysis on multi-option numerical simulation and resistance and self-navigation model test,the the influence of length and cathedral angle of stern flap on the resistance reduction and energy saving in the cruise speed and design speed of displacement surface warship is learned and a preliminary analytical verification of the effectiveness of CFD numerical simulation results is done.[Results]The results show that,by optimizing the stern flap parameters,energy consumption is reduced by 3% in cruise speed and 5% in design speed,thus the goal of energy saving in both cruise speed and maximum speed is achieved.[Conclusions]The research can provide theoretical support for the subsequent parametric optimization design of stern flap of displacement surface warship.
