Modeling and Investigation of the Intensification of Fluid Diffusion in the Capillary-Porous Space by Applying Periodic Pressure Pulsations

摘要

The paper is devoted to the investigation of the possibilities of intensification of fluid diffusion in the capillary-porous space under the influence of superimposed periodic pressure pulsations. The mathematical model of fluid motion in the capillary-porous space is considered in the paper, as well as the technique and experimental setup for determining the viscous and inertial coefficients of hydraulic resistance are described. The results of experimental and numerical studies are presented, which testify to the effectiveness of using modulated oscillations.
