Abstract

Unsaturated flow of liquid in a bed of uniform and spherical ore particles has been studied numerically and experimentally. An unsteady and two-dimensional model has been developed based on the mass conservation equations of liquid phase in the bed and in the particles. The model equations have been solved using a fully implicit finite difference method giving the distributions of the degree of saturation in the particles and in the bed and the vertical velocity of flow in the bed as well as the effect of periodic infiltration on the above distributions. To calibrate the computational model, a series of COLUMN TESTs has been performed using periodic infiltration of water into 40cm high columns composed of ore having particles smaller than 25mm. The numerical analysis shows that (a) the results obtained from numerical MODELING under the same operating conditions as mentioned for COLUMN TESTs, are in good agreement with those from experimental procedure, (b) the degree of saturation of the bed and the time required to reach steady state conditions depend on the inflow of water and intrinsic permeability of the bed and (c) the velocity fluctuations and the fluctuations of the degree of saturation in the bed depend on the inflow of water, period of infiltration, height and intrinsic permeability of the bed.
