Název v původním jazyce

Experimental investigation of development of fully turbulent plasma jet generated by hybrid gas-water torch

Popis výsledku v původním jazyce

Thermal plasma jets are characterized by strong interaction with surrounding atmosphere. Such jets in most cases represent fully turbulent flow. Fast transition of the plasma jet generated by the hybrid gas-water torch to turbulent behavior is caused bya strong difference between ambient air density and density of the plasma, which is extremely low due to high jet temperature. Development of the plasma jet characteristics and mixing of the jet fluid with ambient air along the jet were experimentally studied. Severa diagnostice methods were applied to enable obtaining the properties of the whole jet. The work considers processes in the plasma jet depending on generation conditions. Aec current and flow rate of the plasma forming gas, which determine properties of the arc and correspondingly of the plasma jet, were varied. The obtained data were applied to analyze heat, mass and momentum transfer in the gas-water jets.
