摘要：

The effect of convergent angle on the non-uniform flow through porous media was studied in a converging permeameter. The scope of the present paper is to present the relationship between Hydraulic Gradient (I) and Froude Number (FK2) for flow through porous media with converging boundaries, using intrinsic permeability (K) as characteristic length, and to also show pictorically the relation between linear parameter, a, and non-linear parameter, b, in terms of Media Constant (CW). In the present case, McCorquodale data of size 1.66 cm was used as media, to develop theoretical curves using friction factor (FK) and Reynolds number (RK) relationship, and verified with the help of existing experimental data of different convergent angles. © 2014 Indian Society for Hydraulics.
