Abstract
The jet of high temperature gas was produced on experimental set-up consisting of a barochamber and a shock tube. At the end of a shock tube the sonic nozzle with a critical section of 4mm in diameter is installed.After reflection of a shock wave Enom the end of a shock tube a volume of gas with stagnation temperature in range T=1000 – 5000°K and pressure ratio in nozzle exit n=5 – 1000 is produced. The process of large-scale vortex formation is registered via the shadow device and interferometry both by a single photographing (duration of flash 30ns) and by a high-speed camera (70 Enames produced in one experiment with frequencies up to 0.5 * 106 Enames/s).
