Experimental Study on the Interaction Between Burgers Vortex and a Solid Particle Using 2D PIV Measurement

Abstract

In recent years, many researchers study on characteristic concentrations of particles in turbulent flows. However, it is difficult to observe experimentally interactions between the particles and turbulent vortices because of strong non-linearity of turbulence. In the present study, we focus on the elementary step of an interaction between single vortex tube and a solid particle in a solid-liquid two-phase flow. Burgers vortex is chosen as single vortex tube. Burgers vortex is the simplest model of turbulence.
