Master's thesis of Engineering: Numerical investigation of transonic buffet control using a two-dimensional bump
The current research is undertaken by performing Computational Fluid Dynamics (CFD) simulations for a 2D aerofoil fitted with a shock control bump at a transonic flow condition. Reynolds-Averaged Navier-Stokes equation coupled with turbulence models is adopted to solve the flowfield. The bump has a conventional geometric feature which consists of a ramp, a crest and a tail, and it has eight variants for which the designed parameters are reasonably specified according to the compressible aerodynamics theory. The bumps are placed at a forward and backward position on the suction side of the aerofoil, on which a shock wave is present.
