Compensating for Charged Particle Dynamics when using PIV diagnostics in Plasmas

Abstract

Plasma actuators have quickly gained popularity in aerodynamic research for their ability to induce air flow without the use of moving parts. Particle image velocimetry (PIV) has been used to quantify the induced air flow. Plasma deposits charge onto the particles, which affects PIV results. Different size particles were used to determine the effect of particle charging. Two particle charging theories have been extended to plasma actuators and compared to experimental results. A simulations was used to calculate plasma parameters necessary for the theories. Similarity parameters were calculated for the plasma actuators and the simulation was scaled down to reduce computation time. The simulation included excitation, ionization, de-excitation, and radiative de-excitation reactions. The plasma structure was compared to spectroscopic experiments in the literature.
