The degree of impregnation was estimated by dual-scale porous media flow models, including microscopic impregnating flow and macroscopic resin flow.
In this paper, we focus on the coupled fluid flow and porous media flow modeled by the non-stationary Stokes-Darcy problem.
Also, a multi-step elementary heterogeneous reaction mechanism for the thermo-catalytic H2 electrode chemistry, dusty-gas model to account for multi-component diffusion through porous media, and plug flow model for flow through the channels are used.
A 42-step elementary heterogeneous reaction mechanism for the thermo-catalytic chemistry in the fuel electrode, the dusty gas model (DGM) to account for multi-component diffusion through porous media, and a plug flow model for flow through the channels are used in the model.
Fractional differential operators appear naturally in modeling many phenomena in various fields of engineering, physics and economics, for example, nonlinear oscillations of earthquakes, seepage flow in porous media and dynamic traffic flow model.
A new coupled saturated porous media flow and reactive transport numerical model: RTAFF, has been developed for the assessment and analysis of complex feedback loops between physical transport, geochemistry, and fluid flows in such environments.
The algorithm is robust and extensible, permitting the incorporation of features such as porous media flow, RANS and LES turbulence models, and semi-/fully-implicit time stepping.
An efficient, non-stiff boundary integral method for the initial value problem for interfacial Darcy flow (which is a model of porous media flow) in three space dimensions is presented.
Macroscopic conductivity is useful in forming macroscopic models for porous media flow applications and in the setting of multiscale fast solvers.
The method is also applied to two model problems from porous media flow, miscible and immiscible displacement.
