Annotation
For identification of vortex structures of a heat flow in a free burning plasma jet a new method is used, which utilize fast imaging methods and computerized image processing. This method allows us to observe genesis of vortexes of a heat flow in a plasma jet, including the changes when a wall barrier is inserted in the jet. These two regimes are typical for behaviour of a plasma jet in technological applications. By varying the flow rate of working gas (argon, 15slm to 150 slm) there appear considerable changes both in time and spatial distribution of vortex fields in the two above regimes
