where ~n is the fiber vector with unit length and the preferred fiber direction and κ describes the dispersion of the fiber orientations around the preferred fiber direction. The Macaulay brackets 〈·〉 take into account that the fibers contribute during tension only. The mechanical properties are derived from combining mechanical and structural properties at the tissue and cellular level obtaine...

The pore-level two-phase fluids flow mechanism needs to be understood for geological CO2 sequestration as a solution to mitigate anthropogenic emission of carbon dioxide. Capillary pressure at the interface of water–CO2 influences CO2 injectability, capacity, and safety of the storage system. Wettability usually measured by contact angle is always a major uncertainty source among important para...

In the past few years, micromodels have become a useful tool for visualizing flow phenomena in porous media with pore structures, e.g., the multifluid dynamics in soils or rocks with fractures in natural geomaterials. Micromodels fabricated using glass or silicon substrates incur high material cost; in particular, the microfabrication-facility cost for making a glass or silicon-based micromold ...

The capillary pressure-saturation relation is one of the key constitutive equations used for modeling multiphase (or partially saturated) flow in porous materials. It known that this empirical depends strongly on dynamic conditions, but impact a heterogeneity interface relationship has been studied less. present study employed optical imaging to visualize two-phase drainage under different inje...

We present results of lattice-Boltzmann simulations to calculate flow in realistic porous media. Two examples are given for lattice-Boltzmann simulations in twoand threedimensional (2D and 3D) rock samples. First, we show lattice-Boltzmann simulation results of the flow in quasi-two-dimensional micromodels. The third dimension was taken into account using an effective viscous drag force. In thi...

A micromodel of a program is a tiny, abstract model that captures some crucial aspect of its functionality. To improve the reliability of software, implementations are developed hand-in-hand with micromodels. The code is then checked for conformance with all the relevant micromodels. Micromodels can also themselves be simulated and checked for internal consistency.

Abstract Micromodel can provide valuable information to improve understanding of pore-scale transport phenomenon and also be utilized simulate the process at pore scale. This research aims propose settlement option for quantification suspended solids in micromodel. The micromodel is used mimic formation damage which occurs reservoir that could simultaneously affect enhanced oil recovery. done b...

Enhanced oil recovery (EOR) is a crucial technology in the petroleum industry, influenced by several factors, including flooding fluids and methods. The adjustment of injection strategies application vibration stimulation can significantly impact recovery, especially residual oil. In this study, we conducted experiments using glass micromodel to investigate effect pulsing water on recovery. Our...
