Summary
A numerical method based on the Euler/boundary layer coupling has been extended to unsteady flows to investigate the control of shock wave/boundary layer interaction in transonic flow for the reduction of both, drag and buffet effects. Applications concerned the effectiveness of suction and of a bump at Mach numbers prior to and beyond buffet onset. Good agreement with experiments has been found for the pressure distributions, while the prediction of buffet onset is consistent with other methods, but quantitative differences have been found. Results clearly indicate that control devices can be helpful in reducing drag and in delaying buffet onset to higher lift coefficients or Mach numbers.
