Abstract
ABSTRACT Flow behaviour through porous media with converging boundaries is analysed theoretically and the modifications in the Forchheimer equation needed to incorporate the effect of convergence are brought out. An experimental investigation on the effect of convergence factors on the resistance law relating friction factor (fR) and Reynolds number (RR) using the hydraulic radius as the characteristic length was carried out in a Convergent flow permeameter. In the present case, crushed rock of size 4.93 mm were used as media and water as fluid, to study the variation of friction factor (fR) and Reynolds number (RR) with different ratios of the width and with convergence factors.
