This paper shows a method of symmetrization of an asymmetric flow of a vis-cous incompressible fluid in a flat diffuser using a weak periodic vibration ef-fect on the velocity input flow. The results are obtained for a viscous incom-pressible fluid by simulation based on numerical solving of the Navier-Stokes equations. The results of numerical simulation have shown one of the ways of symme-trization of asymmetric laminar flows of a viscous incompressible fluid in a flat diffuser with a weak periodic effect on the input flow velocity. It is shown that vibration effects, even at amplitudes less than 1% of the velocity can symmetrize the fluid flow in the diffuser. Richardson's "annular effect" for a harmonic oscillating fluid flow in the diffuser was shown.
