5Metamodeling-based parametric optimization of DBD plasma actuation to suppress flow separation over a wind turbine airfoil model显示文摘While dielectric-barrier-discharge(DBD)based plasma actuation systems have been successfully demonstrated to suppress massive flow separation over wind turbine blades to reduce the transient aerodynamic loadings acting on the turbine blades,it is still a non-trivial task to establish a best combination of various operating parameters for a DBD plasma actuation system to achieve the optimized flow control effectiveness.In the present study,a regression Kriging based metamodeling technique is developed to optimize the operating parameters of a DBD plasma actuation system for suppressing deep stall over the surface of a wind turbine blade section/airfoil model.The data points were experimentally obtained by embedding a nanosecond-pulsed DBD(NS-DBD)plasma actuator at the leading edge of the airfoil model.The applied voltage and frequency for the NS-DBD plasma actuation were used as the design variables to demonstrate the optimization procedure.The highest possible lift coefficient of the turbine airfoil model at deep stalled angles of attack(i.e.,α?=?22°and 24°)were selected as the objective function for the optimization.It was found that,while the metamodeling-based procedure could accurately predict the objective function within the bounds of the design variables with an uncertainty~?2%,a global accuracy level of~?97%was achieved within the whole design space.Ramsankar Veerakumar Vishal Raul Yang Liu Xiaodong Wang Leifur Leifsson Hui Hu 2020Acta Mechanica Sinica2020,36,2:1
