摘要
为提高喷水推进三体船的自航性能,该文采用基于仿真设计(SBD)方法,结合船体几何重构、CFD水动力预报、试验设计方法、近似模型和粒子群算法等技术搭建了多目标优化框架,对喷水推进三体船进行了“船体+喷泵”自航性能数值优化研究。优化结果表明:在设计速度下,三体船阻力降低3.9%,推进效率提高4.4%;流道进口前型线变平和减小喷水推进器布置距离,有利于喷水推进器推进性能的提高;尾封板向上提升,可使船体阻力下降的同时,增加推进器的推力。该文可以更好地理解船体型线及喷水推进器布置对喷水推进船阻力和推进性能的影响,具有一定的学术科研价值和工程实用价值。
In order to improve the self-propulsion of a waterjet propelled trimaran,in this paper a multi-objective optimization framework is constructed by using the simulation based design(SBD)method,and combing the hull geometry reconstruction,CFD hydrodynamic prediction,experimental design method,surrogate model and particle swarm optimization algorithm.The numerical optimization of the self-propulsion performance is studied by considering the interaction of the hull and the waterjet system.The optimization results show that at the design speed the resistance of the waterjet propelled trimaran is reduced by 3.9%,and the propulsion efficiency increases by 4.4%.It is beneficial to the propulsion performance of the waterjet system,when the plan lines in front of the intake of the duct become flattened and the arrangement distance of two waterjet system is reduced.The raise of the height of the transom can reduce the resistance of the hull and increases the thrust of the waterjet.In this paper,the influence of plan lines and arrangement of waterjet system on the resistance and propulsion performance of a driven ship can be understood deeply.Present paper has certain academic research value and engineering practical value.
