Intensification of energy exchange in a heterogeneous plasma jet by modulation of the electric parameters of the plasma-spraying process

  • Published:
Journal of Engineering Physics and Thermophysics Aims and scope

The possibility of intensification of the energy exchange in a heterogeneous plasma jet produced by a plasma generator with the use of artificial turbulization of this jet and generation of shock waves in it as a result of the modulation of the electric parameters of the plasma-generator arc was proved. The influence of this modulation on the gas-dynamic parameters of the plasma and the energy state of the sprayed particles was estimated. The possibility of increasing the velocity of the particles of a dispersed material (by 60%) and the rate of their heating by generation of traveling velocity waves and entropy temperature waves in the plasma jet is demonstrated.
