Abstract: | The influence of rotary rear cylinders on a nonstationary wake behind a rounded-off plate is analyzed numerically based on
the solution of nonstationary Navier-Stokes equations on multiblock computational grids by the finite-volume method. It is
shown that the von Kármán vortex trail, which develops behind the body to the point of formation of a virtually steady jet
flow, substantially weakens as the rotational velocity of the cylinders increases.
