| Abstract | This theoretical investigation considered the characteristics of
pore-size distribution of a medium and its applications. An equation relating the effective saturation with capillary pressure was proposed as the pore-size distribution function of the medium. Theoretical equations of relative hydraulic conductivity for wetting and non-wetting fluids were developed as functions of capillary pressure and saturation using the pore-size distribution proposed in this study. The theoretical equations were then verified by experimental
data obtained by previous investigators. The pore-size distribution function was also applied to solve two case studies of drainage problems, viz., one-dimensional vertical drainage of initial saturated media and two-dimensional drainage into
open ditches or tile drains. The analyses were made by considering the porous media to consist of a bundle of capillary tubes and a pad of Hele-Shaw models respectively for the one-dimensional and two-dimensional drainage problems. The total discharges through the porous media were then equal to the summation of the discharge in each capillary tube and Hele-Shaw model. The pore-size distribution was used as the
weight function in the summation. The theoretical solution of the one-dimensional drainage was verified using numerical and experimental results from previous investigators. |
