Ecuación de flujo equivalente para medios porosos saturados heterogéneos
(2012-11-05)
The classical flow and transport equations in porous media assume local equilibrium in a representative elementary volume. However, in reality, a non-equilibrium behaviour is frequently observed, manifested as a delayed ...
Saturation hysteresis effects on the seismic signatures ofpartially saturated heterogeneous porous rocks
(Blackwell Publishing Ltd, 2019-09-13)
Experimental evidence indicates that the spatial distribution of immiscible pore fluids in partially saturated media depends on the flow history and, thus, exhibits hysteresis effects. To date, most works concerned with ...
Capillary pressure-saturation curves of thin hydrophilic fibrous layers: effects of overburden pressure, number of layers, and multiple imbibition-drainage cycles
(Sage Publications Ltd, 2019-12-01)
Unsaturated fluid flow in thin porous media depends on hydraulic properties, such as the capillary pressure, P-c, as a function of saturation, S. We measured this relationship for two different types of compressible thin ...
Effect of soil textural characteristics on longitudinal dispersion in saturated porous media
(Sciendo, 2021-06-01)
This study focuses on the effects of soil textural heterogeneity on longitudinal dispersion under saturation conditions. A series of solute transport experiments were carried out using saturated soil columns packed with ...
Estudo numérica do processo de deslocamento de fluidos em meio poroso heterogêneo usando o método de Lattice Boltzmann
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Mecânica e de MateriaisUTFPR, 2018-04-13)
In the present work, the process of immiscible fluids displacement in a heterogeneous porous medium is numerically studied for the purpose of investigating the sweep efficiency during the oil recovery process. The objective ...
