Abstract

Flows in packed beds are encountered in many engineering applications, such as solar thermal energy storages, chemical catalytic reactors, petroleum and civil engineering (oil and water filtering systems), magnetic refrigerators, biological tissues, and nuclear reactors. Unfortunately, complex geometries and randomly connected void spaces within packed beds have hindered efforts to characterize the underlying transport phenomena. Fully leveraging the advantages of this type of packed beds requires a fundamental understanding of flow topology within the randomly packed sphere beds. In this paper, high-fidelity velocity measurements using Time-resolved Particle Image Velocimetry (TR-PIV) at the pore scales and near the wall boundary are performed in the matching-refractive-index (MRI) facility. Effects of the wall boundary, a low bed-to-bead diameter ratio and Reynolds numbers to the flow patterns will be investigated. From the obtained velocity vector fields, the first- and second-order flow statistics will be computed.
