Original Abstract

The described investigation of the free jet generated by hybrid water-argon torch is concentrated on the arc heater output and on the cold part of the jet (T<2500 K). The determination of the water vapour flow produced by water-stabilized torch is rather difficult because it represents almost negligible part of the total flow of cooling water. The initial parameters of the jet at the arc heater output (the flow-rate of water vapour, the total output momentum) are calculated by means of continuity and energy equations using the spectroscopically measured temperature distribution and the calculated values of thermodynamic properties. The conditions in the region with lower temperatures enable the utilization of probe measuring methods. The temperature field is measured by thermocouples and the velocity field is measured by means of cooled dynamic pressure sensor inserted into hot gas flow. The obtained results of mentioned investigations make it possible to determine the shares of water vapour and argon, the distribution of mass fraction and momentum of individual species and the turbulent Prandtl number in the free jet of hot gas mixture (air, water vapour, argon).
