Numerical Analysis of Gasdynamic Characteristics of Vortex Ring

Abstract:

In the framework of the research the authors have solved the problem of formation and dynamics of the vortex ring. Intensive turbulent vortex rings produced by piston generators have been considered. The research has been carried out on the basis of numerical simulations in fluid dynamics program ANSYS CFX using the high-performance computing system. We have obtained the dynamic and geometrical characteristics of the vortex ring on the basis of numerical experiments. The results are in agreement with self-similar law of vortex ring dynamics and experimental results. The authors have analyzed the influence of piston velocity on the vortex ring properties. The structure of the generated vortex ring has been found to be stable, which is important for experimental studies of acoustic properties of this object.
