Periodic transonic flow and control [PDF]
The Aeronautical Journal, 2008 AbstractThe current understanding of periodic transonic flow is reviewed briefly. The effects of boundary-layer transition, non-adiabatic wall conditions and modifications to the aerofoil surface geometry at the shock interactions on periodic transonic flow are discussed.
