Numerical investigation of effect of vortex generators on Bump inlet performance

  • 摘要: 以一种Bump进气道为研究对象,通过在S弯扩压段入口处布置涡流发生器来控制流动分离,减小出口总压畸变。采用CFD数值计算软件对Bump进气道在设计点(Ma=2.0)与非设计点(Ma=1.8,0.8)工况下内、外流场进行计算,分析不同涡流发生器方案的效果。计算结果表明:在设计点工况下,安装涡流发生器能够抑制流动分离,改善进气道流场品质,减小出口总压畸变;在一些非设计点工况下会增大Bump进气道出口总压畸变;Bump进气道总压损失有所增大,不同叶片间距的涡流发生器对总压损失的影响相当。
