摘　　要：针对所研发的高速滑行艇型,采用风洞试验及数值模拟方法研究其在静水面高速航行时的气动阻力特性。其中,数值模拟方法基于雷诺平均N-S方程及Realizable k-ω湍流模型。结果表明:数值模拟结果与风洞试验结果吻合得较好,误差在5%以内,精度满足工程应用要求。同时,数值及试验结果也表明,合理的气动力艉型能有效抑制滑行艇尾部的流动分离以及尾涡现象,使滑行艇气动阻力下降15%左右。In this paper, aerodynamic drag of high speed planning craft advancing in calm water was studied based on model tests and numerical simulation. An efficient and highly accurate numerical method, using Reynolds-averaged Navier-Stokes equations and the realizable k–ω turbulence model, was applied in performing numerical simulations. It is shown that numerical results agree well with those from aerodynamic model tests, with average error less than 5% satisfying the requirement of accuracy for engineering applications. It is proved that aerodynamic accessories can effectively control the air flow surrounding the craft and make the reduction of aerodynamic drag by up to 15% within the range of the advancing speed.
