摘　　要：为了解甲板风及偏流板偏转角对航空母舰舰载机发动机尾流分布的影响,以国外舰载机发动机尾喷口和航空母舰偏流板为研究对象,采用三维雷诺平均Navier-Stokes方程和k-ε湍流模型,借助计算流体力学技术对该舰载机发动机尾流场进行了数值模拟研究。结果表明:尾流场中的高温高速气流主要分布在偏流板与尾喷口之间的区域,随着偏流板偏转角由50°减小为40°,尾流向上偏转的效果随之减弱,且流线的展向分布范围减小,偏流板两侧的非安全区域由31.9 m减小为20.2 m,而偏流板后方的非安全区域则由13.5 m增大为19.4 m;随着甲板风速由0 m/s增大为15 m/s,偏流板后方的非安全区域由17.5 m增大为53.1 m,偏流板两侧的非安全区域由32.4 m减小为17.8 m。数值仿真结果可以用来指导航空母舰飞行甲板上工作人员的安全作业以及舰面设备布局的优化。In order to study the influence of external wind speed on deck and deflection angle of deflector on the wake field of the aircraft engine on aircraft carrier,taken the tail nozzle of aircraft engine and deflector of aircraft carrier in foreign countries as the research objects,the numerical simulation is conducted for the wake field of the aircraft engine by the computational fluid dynamics and 3D Reynolds averaged Navier-Stokes equation and the k-εturbulence model.The results show that the high-temperature and high-speed airflow in the wake field is mainly distributed in the area between the deflector and the nozzle.As the deflection angle of deflector decreases from 50°to 40°,the effect of upward deflection in the wake flow decreases,and the spanwise distribution range of streamline decreases.Also,the unsafe area on both sides of the deflector decreases from 31.9 m to 20.2 m,while the unsafe area behind the deflector increases from 13.5 m to 19.4 m.As the wind speed on deck increases from 0 m/s to 15 m/s,the unsafe area behind the deflector increases from 17.5 m to 53.1 m,while the unsafe area on both sides of the deflector decreases from 32.4 m to 17.8 m.The numerical simulation results can be used to guide the safety operation of the staff on the aircraft carrier flight deck and to optimize the surface equipment layout of the aircraft carrier.
