Vibrational methods for the symmetrization of asymmetric laminar viscous fluid flow in a plane diffuser

TL;DR

This study explores numerical modeling of laminar viscous fluid flow in a flat diffuser, demonstrating that weak harmonic vibrations can effectively symmetrize asymmetric flow patterns.

Contribution

It introduces a novel approach of using low-amplitude vibrations at the inlet or walls to achieve flow symmetrization in laminar viscous flows.

Findings

Flow can be symmetrized with vibrations less than 0.01% of main flow speed.

Vibration at inlet and walls effectively induces flow symmetry.

Numerical modeling confirms the feasibility of vibration-based flow control.

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
