摘要：
In order to carry out the experimental investigation on control of stall flow over airfoil, two forms of the vortex generator layouts were designed. Comparison for the experimental data with and without vortex generators has been carried out, and the attention are focused on effects of stall flow over airfoil with different vortex generators layout. Experiment shows that the stall flow over airfoil is suppressed evidently by the first and second categories vortex generators, and the maximum lift coefficient is increased dramatically. The control of stall flow over airfoil with the second category vortex generator is much better than the first category vortex generator, and the smaller the inclined angle of the vortex generator is, the better the control effects of stall flow over airfoil will be.
