Смешение подземных вод разного состава в трещиновато-пористых средах

Смешение подземных вод разного состава в трещиновато-пористых средах

Abstract

The mass transfer of groundwaters of different compositions in saturated cracked-porous media has been studied for the case of one-dimensional filtration. The solubility of the porous matrix substance due to the influence of the liquid entering the medium through the cracks has been taken into account. Using the Laplace transformation, an analytical solution to the problem of determining the concentration of the solute generated during such mass transfer has been obtained. The results of the corresponding calculations for the solute concentration distribution at different time points are given.

Исследован массоперенос при одномерной фильтрации в насыщенной трещиновато-пористой среде подземных вод разного состава. Учтена растворимость вещества пористой матрицы под действием жидкости, поступающей в эту среду по трещинам. С использованием преобразования Лапласа найдено аналитическое решение задачи об определении концентрации раствора, образующегося при таком массопереносе. Приведены результаты соответствующих расчетов распределения концентрации в различные моменты времени.
