TBL and CBL Jet Injection Effects on Performance of SD7003 at Low Reynolds Number

Blowing crossing the boundary layer have been widely implemented on the airfoils top surface to control the flow field. This technique has significant effects on the aerodynamic characteristics of the airfoil. This method was applied to SD7003 airfoil at Reynolds number of 60,000. The TBL (Tangential of Boundary Layer) and CBL (Cross to Boundary Layer) have been implemented. Results showed that application of active flow control method caused a reduction in flow separation zone which resulted in improvement of aerodynamic coefficients.
