摘要：

Flow separation on the flap of a high-lift device degrades the overall aerodynamic performance and hence results in a drop in the lift coefficient. However, by employing the active flow control techniques, separation can be delayed and thus the lift can be enhanced. In these methods, the flow is controlled by varying the parameters of actuation. In the present work, the optimal set of actuation parameters is found using the gradient-based optimisation algorithms combined with an accurate and robust discrete adjoint method for unsteady RANS. Numerical results are presented for the optimal separation control on the flap of a high-lift configuration over a large time interval.
