INVESTIGATION OF ENERGY TRANSFER IN A TUBE ARC HEATER.
Abstract
Research is reported on the mutual interaction of an electric arc and a gas flow passing concurrently through a cylindrical tube. The problem considered is that of analyzing the flow and energy transport processes near the inlet region of the tube, under conditions where the diameter of the region containing the gas heated by the arc discharge is smaller than the diameter of the tube. Experimental data are presented for a tube, 3/8 inch in diameter, wherein helium gas is heated to bulk stagnation enthalpies above 20,000 B/lb. The data include the axial distributions of the heat flux to the tube wall, the potential distribution along the arc, the total voltage and current of the arc, and the distributions of the properties of the jet measured by means of a probe. An analysis of the flow and energy transport phenomena, based on the recent methods of laminar flow theory, is presented. The methods yield a system of simultaneous ordinary differential equations describing the flow field. Numerical computations are included. (Author)
