The Using of Kriging Method in DBD Model Parameters Identification

There are certain empirical parameters in the DBD(dielectric barrier discharge) plasma actuators modeling, and these parameters need to be calibrated through some special experimental. In this paper, a parameters identification system for the model proposed by Shyy et al is established via the Kriging model and GA(Genetic Algorithm). The plasma active region profile and the maximum electric field intensity E0 are chosen to be identified. This paper compares different results calculated by various objective functions in order to select the most accurate and steady function. Finally, new plasma active region outline and the expression of E0 are rebuilt to acquire a more accurate DBD plasma actuators modeling. Using the new model, the effect of DBD plasma actuator on controlling the tip clearance leakage flow is investigated. © 2019, Science Press. All right reserved.
