Abstract

A new method for joint determination of the hydraulic permeability of a porous structure and its capillary radius based on the Unarokov equation is developed., describing the kinetics of fluid absorption into a capillary-porous sample against gravity. The determination of these physico-technical characteristics of the porous structure is carried out on the basis of the results of two measurements of the coordinate of the motion of the capillary front and the time of the process in the framework of the experiment on absorbing liquid into the sample. The calculation of the hydraulic permeability and the capillary radius of the porous structure are based on the exact approximation of the Unarokov equation obtained in this paper by the Newton’s binomial
