摘　　要：建立考虑纵倾角及重心升沉等姿态变化的喷水推进三体船阻力数值计算方法,并与船模拖曳阻力试验进行对比,再开展船模自航试验的数值模拟,分析数值计算与模型试验的误差。通过数值模拟可以进一步得到喷水推进器上各部件的受力情况、泵的流量、扬程及其他流场信息,为研究船体与喷水推进装置的相互作用影响规律以及喷水推进与高速三体船的总体匹配设计提供参考。The numerical calculation method has been developed for the resistance of a water-jet propelled trimaran considering the variations of ship attitude,such as the pitch angle and the center of the gravity in comparison with the resistance model test.It also carries out the numerical simulation of the self-propulsion performance for the water-jet propelled trimaran,and thus the analysis of the differences between the numerical calculations and experimental results.The numerical simulation results,including the force of each component on the water-jet propulsor,the flow rate of the pump,the head and other flow field information,can provide reference for the investigation of the interaction between the hull and the water-jet propulsion and the overall matching design of the water-jet propulsor and the high-speed trimaran.
