In a study, particle image pairs of the induced velocity emanating from the dielectric barrier discharge plasma actuator (DBDPA) are acquired for several amplitudes of applied voltage. The detailed averaged velocity distribution is estimated using the single-pixel ensemble correlation (SPC) method at a spatial resolution, which is higher for plasma actuator characterization than any other results using conventional spatial correlation (CSC) method. The averaged velocity distributions from the SPC and CSC methods are compared, and the effectiveness of the SPC method in characterizing the induced flow of plasma actuators is evaluated. In addition, the body-force distribution is estimated from the averaged velocity distribution obtained by the SPC method and compared with that of the CSC method.
