Capillary Pressure Driven Water Movement in Wet Unsaturated Porous Media: Effect of Particle Electric Charge
نویسنده
چکیده
Experimentos do fluxo da água usando um meio poroso não saturado compoto por diferentes sistemas de aalumina molhada não-saturada indicam que a carga superficial da partícula diminuiu com o aumento da água movimentada. O movimento máximo de água ocorreu quando a carga superficial era zero. O movimento da água foi afetado pela espessura da dupla camada elétrica no pH em que as partículas têm carga líquida (a partir do IEP pH ). Estes resultados sugerem estruturação da água, induzida por carga, adjacente a superfícies de partículas carregadas.

An Analytical Solution for One-dimensional Horizontal Imbibition in a Cocurrent Flow
Cocurrent spontaneous imbibition (COCSI) of an aqueous phase into matrix blocks arising from capillary forces is an important mechanism for petroleum recovery from fractured petroleum reservoirs. In this work, the modeling of countercurrent imbibition is used to develop the appropriate scaling equations. Considering the imbibition process and the water and oil movement respectively as the wet p...
متن کاملStudy of Two Phase Fluid Flow in Water Wet Reservoir Rocks by Using X-Ray In situ Saturation Monitoring
Displacement of oil and water in porous media of reservoir rocks is described by relative permeability curves, which are important input data for reservoir performance simulation and drive mechanism studies. Many core studies, such as multiphase relative permeability, capillary pressure and saturation exponent determination, depend on the volume fractions of multiphase flui...

Background and aims: One of the modern ways introduced nowadays for increasing the collection efficiency of particulate, is the use of electric charge in wet scrubbers. These systems can be used in places in which scrubbers are suitable for contaminant collection. In fact, this system only increases the collection efficiency, and it is not a new technology for contaminant collection. Method...
متن کاملFractional wettability effects on two-and three-fluid capillary pressure-saturation relations
Studies of the relation between capillary pressure (Pc) and fluid saturation (S) for porous media containing oi l -water or a i r -o i l -water , often assume that the medium is strongly water-wet. Natural porous media, however, are composed of a variety of mineral constituents; such media are typically composed of waterand oil-wet fractions. This study reports on twoand three-fluid Pc-S data f...
متن کاملApplications of hydraulic properties models on microscopic flow in unsaturated porous media
Several existing equations for solving the non-linear soil-hydraulic properties are introduced and validated to field and laboratory measured data. Models for non-linear hydraulic properties of unsaturated porous media arise from statistical and mathematical fit through the measured data and they can be expressed in forms of unsaturated permeability versus either pressure head or volumetric moi...
