BASIC STUDY OF ENERGY EXCHANGE PROCESS BETWEEN AN ELECTRIC ARC AND A GAS FLOW

Abstract

SPARK STABILIZATION BY A GAS VORTEX. (AD-228 775): Three experimental studies were conducted. The first demonstrated photographically the stabilization of a spark by a gas vortex during the initial phase of the electrical breakdown. A relatively thorough investigation of the radial pressure distribution in the vortex was conducted. A photographic study was carried out to give data on the expansion of the spark channel with time and to note if instabilities develop in the spark. CONTINUOUS HIGH-TEMPERATURE GAS FLOW FACILITY (AD-225 412): The plasma-flow facility has a flow of gas heated by a gas-stabilized arc capable of heating flow of argon to more than 10,000 K. An attempt was made to measure the average electrical conductivity of the plasma over the cross section of the tube. The conductivity was on the order of 1 mho/cm. Two simple experiments were performed which demonstrate the usefulness of the plasma-flow facility as a tool for studying magnetohydrodynamic interactions. THEORETICAL STUDY OF THE FLEXURE OF AN ARC POSITIVE COLUMN (AD-228 540): It was found that when a planar zone of ohmic heating is subjected to a uniform normal flow, an asymmetrical temperature distribution develops with a shift of the peak downstream. It appeared that the resulting curvature of the zone would give rise to two local reactions. AD-263 20310N5 AD-263 204Div. 22U (TIPSB/LH) OTS price $5.60 Professional Design Co., Agawam, Mass.
