N2 - An numerical study of control of flow separation over a NASA hump is conducted by employing a uniform blowing jet and a synthetic jet. The numerical simulations are performed using the commercial software ANSYS Fluent at Mach number Ma = 0.09 and chord Reynolds number Rec = 1 ×106. Reynolds-Averaged Navier-Stokes (RANS) equations are solved in conjunction with the Spalart-Allmaras (SA) and SST k-ω turbulence models. The numerical results show good agreement with the experimental data. Two active flow control techniques, namely the uniform blowing jet and a synthetic jet are employed on the hump to reduce the flow separation. The results show that, for uniform blowing jet, when jet velocity is greater than 85m/s, the flow fully reattaches to the surface. For synthetic jet, when equivalent velocity is greater than 49m/s, the flow fully reattaches to the surface.
