Description
Summary:In this study, numerical simulation method is applied to analyze the aerodynamic characteristics of the airfoil influenced by the parameters of the jet port. The NACA0012 airfoil is studied by using the incompressible Navier-Stokes equations with the structural grid. The influence of air-blowing speed, width, position of the jet and angle of attack on the aerodynamic characteristics of the airfoil is presented. The results show that, for the airfoil, the lift coefficient can be impacted by blowing speed, width and position of the jet to a certain extent. Jet control can reduce the stall angle of attack of the airfoil, but before the stall angle of attack, the effect of lift-increase is almost same at different angle of attack. A basis for the jet design and the selection of jet position along the wing is provide.
