“…Plasma actuators create a plasma above a blunt body that modify the laminar-turbulent transition inside the boundary layer [5,6], even at a high angle of attack [2,7] they induce or reduce the fluid separation, and thus reducing drag [1] and increasing lift [8,9,10]. They also allow sonic boom minimization schemes [11,12], avoiding unwanted vibrations or noise [13,14], sterilizing or decontaminating surfaces and even frost removal [15] on any airfoil, jet engine or wind turbine, through pure electromagnetic control. Its promising potential extend to flow control at hypersonic speeds [16,17] (while still using a jet-reaction aircraft propeller).…”

The asymmetrically mounted flat plasma actuator is studied using a self-consistent 2-DIM fluid model at atmospheric pressure. The computational model use the drift-diffusion approximation and a simple plasma phenomenological kinetic model. It is investigated its electrical and kinetic properties, and calculated the charged species concentrations, surface charge density, electrohydrodynamic forces and gas speed. The present computational model contributes to understand the main physical mechanisms and methods to improve its performance.
