Abstract

We present a study of preferential concentration with Voronoï diagrams of finite size solid particles in a von Kármán flow. This flow is an interesting case of strongly inhomogeneous turbulence with high \(Re_{\lambda }\). We investigate preferential concentration of PMMA particles with density \(\rho _p=1400\) kg/m\(^3\) and diameter \(2.8<d_p/\eta <6.3\) for \(340<Re_{\lambda }<810\). We conclusively find that particles form clusters and voids. The geometry of these structures is therefore studied, and results compared with previous works in other flows.
