摘要

Abstract The purpose of this study is to present a detailed review of the co-flow jet (CFJ) method applied to improve the aerodynamic performance of aircraft. This active flow control technique has been extensively implemented in fixed and rotary wings, wind turbines and ducts to improve aerodynamic performance while reducing the weight, drag and runway distance. Almost all the works in simulations found in the reported literature are performed using CFD software mostly using RANS solver, while a few other solvers have also been reported. Very few experimental studies on aerodynamic performance improvement using wind tunnels are available on the CFJ mechanism. The parameters under study include injection and suction velocity, injection and suction diameter, Reynolds number, Mach number, etc., applied to different phases of flight aiming at delaying the flow separation. This review facilitates the understanding of the research gap that exists in using an active flow control mechanism in the CFJ method.
