Abstract
The purpose of this paper is to present a simple analytical model to describe the flow of a dilute colloidal silica dispersion through a porous medium column. The model presents the movement with time of the interface between the dispersion and the water it displaces, the velocity of the interface, and the time-varying discharge through the medium. The effects of both viscosity difference and density difference of the displacing dispersion are included. Results of the model compare favorably with measurements of flow through sand columns 0.914 and 3.05m long. The viscosities of the dispersions were approximately twice those of the water they displaced and the density was about 8.3% higher. The model is expanded by using a numerical scheme to predict the interface velocity for dispersions having linear and exponential time-varying viscosities.
