Abstract
A prerequisite for aeroelastic stability prediction in turbomachines is the understanding of the fluctuating aerodynamic forces acting on the blades. Unsteady transonic flows are complex because of mutual interactions between travelling pressure waves, outlet disturbances, shock motion, and fluctuating turbulent boundary layers. Complex phenomena appear in the shock/boundary layer region and produce phase lags and high time harmonics, which can give a significant contribution to the overall unsteady lift and moment, and therefore affect flutter boundaries, cause large local stresses, or even severely damage the turbomachine.
