| description | 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-ε turbulence 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. |
