Abstract
Abstract: This work presents the study of the discharge plasma actuator. The physics of the plasma
discharge has been studied by solving partial differential equations. Plasma characteristics were
obtained and analyzed for a voltage applied level. Based on this data electrostatic, models have been
developed. The time-dependent charge distribution was used to provide boundary conditions to the
electromagnetic field equation that were used to calculate the actuator body force vector. Numerical
simulations were performed to study the effect of the plasma body force on the neutral fluid.
The density of the positive and negative charges will be equal in the bulk of the plasma. Only on the
edges will there be a charge imbalance, due to the thermal motion of the particles. The thickness of the
regions along the edges in which the plasma supports a net positive or negative charge density is
determined by Debye length.
