"The aim of the study rests with analyzing the onset and time evolution of the dynamical processes in plasma flows. The crucial information is obtained by measuring the radiation intensity in the core of the jet, scanned by the CCD cameras from two mutually perpendicular directions. Quasi-stationary regimes of plasma jets are usually characterized by local vortex structures in heat flows, noted for dynamical changes of vorticity along the axis of the jet. The variant discussed in the paper makes it possible to identify the changes in dynamics by determining a three-dimensional course of the heat flow vector."@en . . . .
