AN INVESTIGATION OF THE WALL-STABILIZED, TRANSPIRATION-COOLED DC ELECTRIC ARC.
Abstract
An extension of previous investigations of a wallstabilized, transpiration-cooled DC electric arc plasma generator was made. Numerical solutions for the energy exchange in the arc were obtained, and an extended theoretical model for the energy exchange was proposed. Measurements of radiative power losses indicated that use of the extended model may be necessary for accurate quantitative analysis, particularly in predicting the radiative losses. Investigation of an unusual spatial electric field strength fluctuation in the arc indicated that experimental error probably did not account for the observation. The latter assertion is upheld by other experiments performed on similar devices at the University of Minnesota. Spatially nonuniform gas-injection patterns were found to improve the energy-conversion efficiency of the device. Means of further increasing the efficiency, and of extending the theoretical analysis of the device, are proposed. (Author)
