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.
