## Numerical simulation of the flowfield around helicopter engine inlet

• 摘要: 对直升机发动机入口处流场采用有限体积法,通过生成贴体结构化网格求解Navier-Stokes(N-S)方程, 进而对MI-171直升机低空悬停和前飞状态进行数值模拟,计算了该型直升机发动机进气道处的流场特性.然后以广义尾流入手,并引入尖涡涡核作用的半经验修正的旋翼自由尾流模型对该机发动机进气道处流场进行计算分析.对沿发动机轴线剖面以及垂至于该轴线剖面的分析结果表明,CFD(Computational Fluid Dynamics)数值模拟方法与旋翼自由尾流分析方法均可以对涡诱导流场进行预测.
