Beschreibung
Zusammenfassung:	Numerical modeling of the interaction of a vortex ring with a normally located flat obstacle was performed based on the nonstationary Navier–Stokes equations, for discretization of which the finite volume method was used. A qualitative picture of the change in the structure of a vortex ring during its interaction with the obstacle is presented. The distributions of pressure in time on the obstacle and the change in the longitudinal force acting on the obstacle are determined.
