Effect of the relative location of the droplets and the structure of a porous medium on the rate of absorption and distribution of a liquid

摘要: The present work focuses on numerical simulation of the sequential absorption two droplets at an arbitrary location surface single-and double-layer porous media. For description fluid flow from a droplet into medium, Euler equations taking account tension forces were used together with unsteady filtration equations. layers media characterized by effective permeability coefficients dependent porosity and pore size. change in shape during absorption, propagation absorbed fields velocities pressure are output data problem. effect medium structure parameters relative rate distribution liquids is analyzed using experiment. It shown that presence second layer can significantly affect duration result absorption. ratio size found to be main parameter governs layer.
