Aerodynamic Performance Analysis Of Co-Flow Jet Airfoil, C M Vigneswaran, Vishnu Kumar G C
Aerodynamic Performance Analysis Of Co-Flow Jet Airfoil, C M Vigneswaran, Vishnu Kumar G C
International Journal of Aviation, Aeronautics, and Aerospace
The work in this paper aims to increase the maximum lift coefficient of the airfoil by implementing the co-flow jet concept on NACA 0018 airfoil and also to investigate the performance of co-flow jet (CFJ) airfoil. To conduct numerical solution, RANS equations have been solved for 2D incompressible and unsteady flow using the Spalart-Allmaras turbulence model. The suction surface of the airfoil is modified by placing the injection slot near the leading edge and the suction slot near the trailing edge. A small mass of air is withdrawn into the airfoil suction slot, pressurized by a pumping system located inside …
