Wind tunnel similitude criteria for fluid flow in macro-porous materials

Abstract

A wind tunnel experimental set-up was performed at CRIACIV (Inter – University Research Centre on Building Aerodynamics and Wind Engineering) Boundary Layer Wind Tunnel Laboratory at the University of Florence, with the aim of determining some possible similitude and scaling criteria. The pressure drop and the drag force on the porous material obtained at different air velocities were measured for twenty five porous samples with porosities ranging from 0.2268 to 0.6940
