Formation of powerful plasma flow from substance of liquid electrolyte cathode

The process of plasma flow formation using an electric discharge with liquid electrolyte cathode in the power range (25–39) kW was experimentally investigated. The discharge was created inside the chamber with walls of refractory material at a distance of 20 cm between electrodes. Sodium chloride aqueous solutions with concentrations of 0.1–0.2 mol·l⁻¹ were used as electrolyte. The optimal conditions are revealed under which the heat losses on the electrodes are reduced. Plasma stream with a mass rate of 1.0–1.7 g·s⁻¹ was obtained. (paper)
