Abstract

The objective of the present study is to elucidate the flow mechanism of delaying stall by use of a wavy leading edge. Experiments were carried out to examine the effects of various shapes of wavy leading edges. Numerical simulations were also carried out to investigate the flow around wavy leading edge. It is found that the wavy leading edge can restrain flow separation and delay stall. The shorter wavelength of protuberance is the better for producing large lift force at poststall angles of attack on rectangular wing.
