We study mixing in the presence of convective flow in a porous medium. Convection is characterized by the formation of vortices and stagnation points, where the fluid interface is stretched and compressed enhancing mixing. We analyse the behaviour of the mixing dynamics in different scenarios using an interface deformation model. We show that the scalar dissipation rate, which is related to the dissolution fluxes, is controlled by interfacial processes, specifically the equilibrium between… 

Modeling the Transient Effects of Pore-Scale Convection and Redox Reactions in the Pseudo-Steady Limit

We introduce theory to study the convection of active species with redox reactions at solid/solution interfaces within porous media, motivated by applications in energy storage devices where cyclic

Identifying Stagnation Zones and Reverse Flow Caused by River‐Aquifer Interaction: An Approach Based on Polynomial Chaos Expansions

Fluctuating stream stages and peak‐flow events can significantly influence the interactions between streams and aquifers and modify the hydraulic gradient, the flux exchange and the subsurface flow

Theoretical Analysis of Groundwater Flow Patterns Near Stagnation Points

The importance of stagnation points for characterizing groundwater flow patterns has long been recognized. However, the possible streamline configurations near stagnation points under the constraints

Flow Pattern Map of Flow Boiling in a Rectangular Channel Filled with Porous Media

A flow visualization study was carried out for flow boiling in a rectangular channel filled with and without metallic random porous media. Four main flow patterns are observed as intermittent

Time-Resolved PIV Measurements and Turbulence Characteristics of Flow Inside an Open-Cell Metal Foam

TLDR
A TR particle image velocimetry (PIV) method is introduced for use inside open-cell metal foam structures to understand the flow characteristics inside metal foams and the span-wise vorticity fluctuation through the foam arrangement is presented.

Heterogeneity‐Induced Mixing and Reaction Hot Spots Facilitate Karst Propagation in Coastal Aquifers

The freshwater‐seawater mixing zone is a critical region for chemical activity. Yet little is known about the influence of ever present spatial heterogeneity on the dynamics of mixing and calcite

Flow dynamics and heat transfer in partially porous microchannel heat sinks

In this study, the flow dynamics and heat transfer in partially filled pin-based microchannel heat sinks (MCHS) are examined. The lattice Boltzmann method is used to analyse the physics of these

Dissolution patterns and mixing dynamics in unstable reactive flow

We study the fundamental problem of mixing and chemical reactions under a Rayleigh‐Taylor‐type hydrodynamic instability in a miscible two‐fluid system. The dense fluid mixture, which is generated at

Scaling of convective mixing in porous media.

TLDR
It is shown that the dissolution flux and the rate of fluid mixing are determined by the mean scalar dissipation rate, which supports the universal character of convective mixing and points to the need for alternative explanations for nonlinear scalings of the dissolve flux with the Rayleigh number.

The lamellar description of mixing in porous media

We develop a general framework for modelling mixing in porous media flows, in which the scalar mixture is represented as an ensemble of lamellae evolving through stretching, diffusion and

Compositional convection in viscous melts

DURING solidification of multi-component melts, gradients in temperature and composition develop on different scales because of the large difference between their respective molecular diffusivities.

TLDR
The initial instability and the quasisteady state are investigated, which have important implications for determining the time scales and rates of dissolution trapping of carbon dioxide in brine aquifers proposed as possible geologic repositories for sequestering carbon dioxide.
