Zusammenfassung:A numerical experiment on investigation of the dynamics of the interaction of three coaxial vortex rings formed from thermics is performed. As a mathematical model of the phenomenon, the system of Navier-Stokes equations for a compressible heat-conducting gas in a cylindrical coordinate system is chosen. The calculations are performed using a finite-difference method based on an explicit three-step scheme of splitting by physical processes. The influence of the position of the thermics on the common axis of symmetry on the character of their motion and interaction is investigated.[PUBLICATION ABSTRACT]
