Abstract
Results of an experimental study of the evolution of a vortex flow formed under the action of a submillimeter arc discharge moving in a constant magnetic field in a supersonic air flow near a flat surface are presented. Owing to the high reproducibility of the discharge parameters and precise synchronization of the equipment, it is possible to study the flow structure in much detail by the methods of particle image velocimetry and Schlieren visualization. It is found that the spaced and time characteristics of the generated vortex structures can be effectively controlled by changing the direction of the electromagnetic force arising during the discharge.
