 <abstract xml:lang="en">
 <p>Based on the Darcy-Brinkman approach for viscous incompressible fluid flow in porous media and a one-parameter representation of local temperature equilibrium, a model of penetration of a Newtonian fluid under gravitational driving force into a semi-bounded porous isotropic medium is proposed. For slow fluid permeation, the hydrodynamic subproblem is simplified by linearizing the velocity field using the ideal plug flow regime within a linear filtration framework. The initial-boundary value problem is formulated for two boundary condition formulations on the "free" surface of the porous layer: constant temperature and its pulsed change. Analytical solutions are obtained in quadratures. A calculation example is given illustrating the effect of non-isothermal flow of a "hot" medium into a "cold" porous structure on the permeation time.</p>

 <p>На основе подхода Дарси-Бринкмана для течения вязкой несжимаемой жидкости в пористых средах и однопараметрического представления о локальном температурном равновесии предложена модель проникновения ньютоновской среды в условиях гравитационной движущейся силы в полуограниченную пористую изотропную среду. Для медленного просачивания жидкости гидродинамическая подзадача упрощена с помощью линеаризации поля скоростей применением режима идеального вытеснения в рамках линейной фильтрации. Начально-краевая задача сформулирована для двух вариантов постановки краевого условия на «свободной» поверхности пористого слоя: постоянная температура и её импульсное изменение. Получены аналитические решения в квадратурах. Приведен пример расчета, иллюстрирующий влияние неизотермичности потока «горячей» среды в «холодную» пористую структуру на время просачивания.</p>
