Numerical modeling of multiphase fluid flow through the electrolytic cell
… anode due to the cell operation. Thus, the fluid flow process in the cell, in general, is a three-phase process that includes turbulence. Although hydrogen bubbles and calcium carbonate particles are usually small in size, they aggregate in the system over time and lead to the blockage of …

Chemical and Thermochemical Wave Behavior in Multiphase Fluid Flow Through Permeable Media: Wave-Wave Interactions
The flow of reactive fluids through permeable media creates regions of constant composition for purely reactive flow. These regions are separated by waves, which mark the change in composition from one region to the next. We develop a theory which elucidates the interactions of these chemical waves …

Preferential mode of gas invasion in sediments : grain-scale model of coupled multiphase fluid flow and sediment mechanics
… We rigorously account for the presence of two fluids in the pore space by incorporating forces on grains due to pore fluid pressures, and surface tension between fluids. This model, which couples multiphase fluid flow with sediment mechanics, permits investigating the upward migration of gas …

Multi-scale Investigations of Geological Carbon Sequestration in Deep Saline Aquifers
… This work focuses on the role of wettability on multiphase flow in porous media, density-driven convection in porous media, and their implications for GCS in deep saline aquifers. Wettability is a critical control over multiphase fluid flow in porous media. However, our understanding on the …

Investigation of meniscus region behavior and oscillation mark formation in steel continuous casting using a transient thermo-fluid model
… of the meniscus region, which includes transient multiphase fluid flow of slag and steel, with low-Reynolds turbulence, heat transfer in the mold, slag, and steel, steel shell solidification, mold oscillation, and temperature-dependent properties. This model was first validated using previous …

Development of a high-order accurate reservoir simulator using spectral element method
… the future performance of a reservoir. Modeling multiphase fluid flow in porous media can be computationally challenging due to heterogeneous geologic features and sharp, moving fluid interfaces. Low-order convergence of conventional reservoir simulators, often based on finite volume or finite …

Nonequilibrium Phenomena in Multiphase Flow, Transport, and Phase Change in Porous Media: Pore-Level Physics, Network Modeling, and Upscaling
Multiphase fluid flow, multicomponent transport, and thermodynamic phase change in porous media are important for many subsurface environmental and energy applications, including vadose zone contaminant transport and shale oil and gas production. Understanding these complex physical processes …

Coupled geomechanics and transient multiphase flow at fracture-matrix interface in tight reservoirs.
… role in the world economy and energy markets. Fluid injection (normally water) forces the hydrocarbons out of the reservoirs. Geomechanics, externally applied stress on the rock, play a significant role in the oil recovery from fractured reservoirs. Subsurface fluid injection modifies pore …
