Two-Dimensional Modeling of the OAUGDP

Summary form only given. The development of the one atmosphere uniform glow discharge plasma (OAUGDPtrade) has made possible to generate purely electrohydrodynamic (EHD) body forces. RF displacement currents produces the body forces that accelerate the plasma. Only paraelectric flow acceleration is considered in this work: a plasma is accelerated toward increasing electric field gradients, while dragging the neutral gas with it. Applications: propulsion and guidance systems in aeronautics, killing any kind of bacterium and virus. A 2-dim fluid model of the OAUGDPtrade in staggered geometry is presented. Continuity equations for electrically charged species N₂ ⁺, N₄ ⁺, O₂ ⁺, O₂ ^- and electrons are solved coupled to the Poisson equation, subject to appropriate boundary conditions. It was used an algorithm proposed by Patankar. The transport parameters and rate coefficients for electrons at atmospheric pressure are obtained by solving the homogeneous Boltzmann equation for electrons under the hydrodynamic assumption. It is obtained as a function of time: electric current; surface charge accumulated on the dielectric surface; memory voltage and gas voltage controlling the discharge; spatial distribution of the electric field; populations of charge species; body forces; resulting gas speed.
