英文摘要: The performance of the waterjet depends not only on the performance of its separate component of waterjet pump and inlet duct, but also depends on the matching performace of the pump, inlet duct and hull. This project mainly concerns the multiobjective and multipoint optimization of high performance waterjet pump, optimal design of the inlet duct and the matching between the pump, inlet duct and hull. Contents of this research are: (1) Establishing the parametric design method of the pump meridional geometry, and founding the efficient pump blades design model by solving the three-dimensional inverse design equations and a full three-dimensional viscid flow iteratively. (2) Constructing the multiobjective multipoint optimization model of high performance waterjet pump basing on RSM and Genetic Algorithm, and summarizing the influence gene of design variables on the combination property of the pump. (3)Constructing the parametric design model of waterjet inlet duct, and optimizing the design results by CFD analysis.(4) obtaining the efficiency, cavitaion, and acoustic performance of the nude pump and the pump after hull based on Computational Fluid Dynamics(CFD) and the Computational Acoustics. (5) analyzing the performance and interaction of the full scale "watjet pump + inlet duct + hull" system, and researchin
