Numerical simulations were carried out to investigate the action mechanism of plow vortex generator(Plow VG)on flow control in a low-Mach number high-loaded compressor cascade. An approach installing vortex generators ahead of the blades leading edge was proposed,the change of the performance of the cascade and the structure of the secondary flow in the channel were compared and analyzed. According to the simulation results,vortex(suction/pressure surface vortex)induced by Plow VG is similar to the horsesho...
