Краткое описание

Single-dielectric-barrier-discharge (SDBD) plasma actuators have shown much promise as an actuator for active flow control. Proper design and optimization of plasma actuators requires a model capable of accurately predicting the induced flow for a range of geometrical and excitation parameters. A number of models have been proposed in the literature, but have primarily been developed in isolation on independent geometries, frequencies and voltages. Many of these models rely on parameters that have been calibrated for one specific geometry. This study presents a comparison of four popular plasma actuator models over a range of actuation parameters for three different actuator geometries typical of actuators used in the literature. The results show that the hybrid model of Lemire & Vo (2011) is the only model capable of predicting the appropriate trends in how the body force and induced velocity change for different geometries. Additionally, it is the only model that exhibits a non-linear velocity scaling with voltage with a power law relationship of exponent 1.5, compared to the empirical result of a 3.5 power law found in the literature.
