Research on Aerodynamic Flow Acceleration Induced by One Atmosphere Uniform DBD Plasma Based on PIV

Abstract:

The aerodynamic flow acceleration with one atmosphere uniform induced by dielectric-barrier-discharge plasma actuation were studied based on PIV. The flow fields induced by the dielectric barrier discharge with different discharge models and actuation parameters were investigated. In term of the obtained velocity distributions, a comparative study on the effect of excitation voltages, carrier frequencies, pulse frequencies and duty ratios on plasma actuation was presented and the optimum actuation parameters was provided. The results of this study indicate: 1) The induced velocity increases linearly with excitation voltage and frequency. 2) When f_p<300Hz, the induced velocity rises with the increase of pulsed frequency, but when f_p>300Hz, it shows an opposite tendency.
