This paper presents some recent research results at Cranfield on parametric studies of various shock controls at transonic speeds using Navier-Stokes solutions. The effects of suction, blowing and solid bumps on aerofoil aerodynamic performance have been studied systematically regarding the control location, the mass flow strength and the bump height. Comparisons with experimental data have been made where possible to validate the numerical study. The numerical simulation highlighted the benefits and drawbacks of various types of control for transonic aerodynamic performance and identified some key parameters.
