THERMAL CHARACTERISTICS OF A HIGH AND LOW MASS FLUX ARGON PLASMA JET.

Abstract

The thermal characteristics are determined by the plasma jets emanating from the F40 plasma torch which is manufactured by Thermal Dynamics Corp. A grating spectrometer was used to determine the temperature fields of high and low mass flux jets generated by a 400 amp arc. The temperature distributions in a crosssection close to the nozzle were determined as well for a number of other mass flows at a 400 amp current input. Also, similar distributions were obtained for the high and low mass flux cases at 600 amps. A calorimeter was used to measure the energy output of the torch for various mass flows. Additionally the radiation from the torch was measured with a radiometer. The steadiness of the turbulent high mass flux jet and the meaning of the measured temperatures are discussed in detail.
