Abstract
This study is focused on the motion of a dilute suspension containing rigid, spherical, non-Brownian, noncolloidal particles flowing over and through porous media models. The flow is confined to very low Reynolds numbers. To examine the velocity distribution particle image velocimetry (PIV) was applied in conjunction with refractive index matching (RIM) techniques. This study is the first of its kind analyzing the interaction between two common engineering systems: suspension fluid and porous media.
Highlights
Porous media has been a prevalent structure in both the natural world as well as many manufactured systems
Other studies have focused on using optical experimental techniques to investigate the properties at the interface of a porous media bounded on top by a free flow region
particle image velocimetry (PIV) experiments were developed to identify the effect of the porous media characteristics and different porous media configurations on the overall flow structure and the properties at the interface, Arthur et al (2009); Agelinchaab et al (2006)
