because of electricity subsidies, electricity price in iran is much lower than its real value, and the growth of electricity demand is much more than its rational rate, which in turn implies ever increasing investment in the electricity section by the government. therefore, the recent government policies are based on elimination of electricity subsidies, followed by commissioning complete elect...

We present a self-consistent two-dimensional fluid model of the temporal and spatial development of the One Atmosphere Uniform Glow Discharge Plasma (OAUGDP). Continuity equations for electrically charged species N+2 , N + 4 , O + 2 , O − 2 and electrons are solved coupled to the Poisson equation, subject to appropriate boundary conditions. It was used an algorithm proposed by Patankar. The tra...
