چکیده
Multi-phase flow and transport in porous media is prevalent a wide range of challenging fluid mechanics problems related to sustainability, energy, the environment. Accurate prediction displacement interaction such flows vital addressing these problems. In particular it critical understand small- or pore-scale its spatial temporal evolution, which can impact behaviors at system scales nontrivial manner. Intermittency phenomenon currently observed numerical experimental studies single-phase (Anna et al., n.d.; Morales n.d.), but case multi-phase has yet receive much study due challenges faced both simulations experiments. The underlying physics spreading, mixing, interfacial processes must be understood for accurate predictions systems. Therefore, comprehensive understanding very small necessary development system-scale models. We present results from coordinated intermittency effects over viscous inertial regimes single- 2D heterogeneous micromodels quantify Lagrangian statistics better inform applicability different modeling frameworks as correlated-continuous time random walk tested by studying particle trajectories obtained tracking velocimetry (PTV) measurements Lattice Boltzmann flows. make note influence pore Reynolds number (Re) on intermittency, compare two regimes.

Adaptive fully implicit multi-scale finite-volume method for multi-phase flow and transport in heterogeneous porous media
We describe a sequential fully implicit (SFI) multi-scale finite volume (MSFV) algorithm for nonlinear multi-phase flow and transport in heterogeneous porous media. The method extends the recently developed multiscale approach, which is based on an IMPES (IMplicit Pressure, Explicit Saturation) scheme [P. Jenny, S.H. Lee, H.A.

متن کاملControllability, observability and identifiability in single-phase porous media flow
Over the past few years, more and more systems and control concepts have been applied in reservoir engineering, such as optimal control, Kalman filtering, and model reduction. The success of these applications is determined by the controllability, observability, and identifiability properties of the reservoir at hand. The first contribution of this paper is to analyze and interpret the controll...
متن کاملNumerical Simulation of Three-Phase Flow in Heterogeneous Porous Media
We describe an efficient numerical simulator, based on an operator splitting technique, for three-phase flow in heterogeneous porous media that takes into account capillary forces, general relations for the relative permeability functions and variable porosity and permeability fields. Our numerical procedure combines a non-oscillatory, second order, conservative central difference scheme for th...
متن کاملOperator Splitting for Three-Phase Flow in Heterogeneous Porous Media
We describe an operator splitting technique based on physics rather than on dimension for the numerical solution of a nonlinear system of partial differential equations which models three-phase flow through heterogeneous porous media. The model for three-phase flow considered in this work takes into account capillary forces, general relations for the relative permeability functions and variable...
