ABSTRACT
This paper investigates the performance of controlling Co-Flow Jet (CFJ) on NACA 0025
airfoil at five different Reynolds numbers of 5 · 104, 7.5 · 104, 105, 1.5 · 105, and 3 · 105. To
conduct the numerical solution of the fluid flow, 2D incompressible and unsteady Reynolds-
-averaged Navier-Stokes equations are solved using the SST-k-ω turbulence model. At all
investigated Reynolds numbers, the lift coefficient enhances as the momentum coefficient
increases, and its best performance is obtained at an angle of attack of (AoA) 15◦. It is also
observed that using the CFJ is of greater importance at Re ≤ 105 than in other investigated
cases.
