Modelling the Flow of Water in Stratified Layers of Sand

Abstract

The phenomenon of deflection of flow of water in porous media of different
porosities with porosity ratio,Ψ , is similar to the fact that there is deviation in fluid flow in a pair of media of different densities. Theoretically, the  relationship between preferred direction of flow of water,Θ , and the sand layers of porosity ratio, Ψ was found to be cosΘ = ny while experimentally it was obtained to be cosΘ =1.98 lnΨ + 1.13 (0.5951Ψ0.9634).Thereafter, when the theoretical equation was compared with the experimental result, the value of n ranging from 0 to 1 were found to be appropriate for the theoretical equation to be valid.

Key words: porosity ratio, inlet pipe, outlet pipe, deflection angle.
