      An Experimental and Computational Investigation of Ship Airwakes

      摘要:
      开展了SFS2标准舰船模型空气艉流场风洞试验及CFD仿真计算工作,对比分析了国内外试验及仿真结果,给出了飞行甲板上流场的基本分布规律。结果表明,气流吹过舰体及机库后在飞行甲板上形成了复杂的涡流区,对舰载直升机的飞行安全有直接的影响。
      Abstract:
      A wind tunnel experiment and CFD simulations of the SFS2 simplified frigate ship air-wakes have been performed ? respectively, as well as contrast analysis of the test and the simulation results at home and abroad, providing basic flow field distribution characteristics on the flight deck. The results showed that a complex recirculation zone was formed on the flight deck after air blowing through the hull and hangar, which directly impacted on the flight safety of shipborne helicopters.
