AERODYNAMIC STALL SUPPRESSION ON AEROFOIL SECTIONS USING PASSIVE AIR JET VORTEX GENERATORS

摘要

This paper presents an experimental and computational study of a novel passive version of the air jet vortex generator flow control system for the delay or suppression of trailing edge boundary layer separation and subsequent stall. The results show that a passive vortex generating jet flow control system can effectively delaying trailing edge separation and subsequent stall to higher angles of attack, without the need for any active energy input and without significant drag penalty.
