Abstract:
In order to study the effects of suction locations on the airfoil flow separation control,the two-dimensional compressible Navier-Stokes equations are solved by using HLLC scheme and LU-SGS scheme with the dual-time-stepping technique,and the flow field around the NACA0012 airfoil under the upper airfoil surface suction control is simulated numerically when Re is 6 000.The effects of different suction zone locations on separation suppressions and aerodynamic performances of airfoil are researched.The computational results show that under the same suction coefficient,the suction zone location is the important factor improving the aerodynamic performances of the airfoil effectively.And the control mechanisms are different when the suction controls act at the different suction locations.For the NACA0012 airfoil with the open separation characteristics,the appropriate location of the suction zone is in the leading-edge separation zone.
