RT Journal Article ID 6dec3fb37a7ac74f A1 N, BHANU PRAKASHAM REDDY T1 Effect of Converging Boundaries on Flow Through Porous Media JF Journal of Porous Media JO JPM YR 2005 FD 2005-10-01 VO 8 IS 5 SP 529 OP 539 AB An experimental investigation on the effect of converging boundaries on flow through porous media was carried out in a converging permeameter using crushed rock of size 4.73 mm as the media and water as fluid. The influence of converging boundaries on the resistance law relating the friction factor (fR) the and Reynolds number (RR) using the hydraulic radius as the characteristic length is examined. The present study aims to develop theoretical curves similar to the Moody diagram used in pipes, and to study the variation of fR and RR for different CR values taken as the third parameter for different ratios of the radii and for different radial lines. The relationships existing between the linear parameter a, the nonlinear parameter b, and the hydraulic radius R are also obtained theoretically and are verified with the experimental data.
