Velocity profiles in a random porous bed

Abstract

In this study the velocity distribution of the fluid flow through and over a random porous bed is investigated. The different porous bed and the different porosity influence significantly the form of the velocity profiles. The measurement method should be non-intrusive to avoid any damage to the porous bed and turbulence to the flow. The random and complex structure of the porous bed creates many problems for the researchers because the conditions at the interface are complicated. A series of experiments were conducted with various types of porous beds and the results show that the different type of bed influences with different way the velocity profiles. Also the velocity profiles are found to be dependent on Reynolds number. © 2021 by Begell House, Inc. www.begellhouse.com
