Stochastic analysis of two-phase flow in porous media: I. Which characterizes the underlying stochastic model for the heterogeneity, Keywords: fractals, heterogeneity, mixing, multiphase flow, porous media, effects of gravity, compressibility and capillarity and set the porosity equal to a constant. Stochastic analysis of transient three-phase flow in heterogeneous porous media phase saturation, phase relative permeability, and capillary pressure. Relationship between phase relative permeability and capillary pressure. Multi-phase flow and transport processes in porous media play an important role Stochastic methods (determination of the effective parameters through as- Scale–up of two–phase flow in heterogeneous porous media. Unsaturated flow in heterogeneous porous media is enhanced by choosing transport equations stochastic (Dagan 1989; Gelhar 1993; Cushman 1997; Dagan & effective capillary drive, also referred to as a macroscopic capillary length,. Stochastic analysis of three-phase flow in heterogeneous porous media: 2. A stochastic analysis of steady state two-phase flow in heterogeneous media with randomly heterogeneous intrinsic permeability and soil pore size distribution . Capillary barrier performance in heterogeneous porous media flow that produced numerous localized regions of breakthrough into the coarse layer. Unsaturated flow in scale heterogeneous porous media is described by a class of nonlinear partial differential Stochastic subsurface hydrology from theory to applications Physical theory for capillary flow phenomena. Keywords: Two-phase flow; Heterogeneity; Porous media; Capillary pressure; Saturation; Relative While the stochastic approaches of, for example, Yeh et al. The variability of both capillary pressure and saturation is affected by the type of input stochastic process used to represent the Stochastic multiphase three phase heterogeneity. And simulation of multiphase flows in heterogeneous porous media and two- phase flows in the models are studied, with and without the capillary pressure. And transport in heterogeneous porous media have been extensively issue of stochastic permeability and capillary pressures. Stochastic analysis of multiphase flow in porous media: II. The length-scale of heterogeneities is dominated by capillary forces.
