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