Abstract

This paper presents the results of numerical modeling of laminar flows of a viscous incompressible fluid in a flat diffuser with and without vibration effects. Two methods of flow symmetrization in a flat diffuser are considered: by means of periodic vibration action at the inlet to the diffuser and on its walls. Modeling has shown that it is possible to symmetrize the flow of a viscous liquid in the diffuser by using a weak harmonic vibration action, the speed of which can be less than 0.01% of the speed of the main flow
