【Abstract】

<正>In various practical situations(such as in turbomachines),the free-stream turbulence is one of important factors responsible for excitation of Goertler vortices in boundary layers over concave walls.Amplification of such vortices is able to lead to the laminarturbulent transition and change dramatically the skin friction,heat
