(MS06-B) Interfacial phenomena across scales

Oral Presentation

Bacteria and microorganisms retention during water filtration allows to improve water quality and quantity. For that reason, the mechanisms affecting the propagation and fate of microbial populations need to be study to assess the risks for human health of water renovation technologies as managed artificial recharge.
In this work we study bacteria transport in porous media by means of column...

95. Absorption and diffusion process at the CO2-oil interface considering density fluctuations near the critical CO2 point

Dr Bilal Zulfiqar (Helmholtz Centre for Environmental Research, Leipzig-Halle)

19/05/2025, 11:40

(MS06-B) Interfacial phenomena across scales

Oral Presentation

CO2 injection into geological formations is considered as technologically advanced and economically feasible approach that combines both CO2 sequestration and enhanced oil recovery (EOR). The absorption- and diffusion processes at the CO2-oil interface (under reservoir conditions) plays an integral role in governing key physico-chemical properties such as volume increase, miscibility, density...

148. Phase-field modeling of snow microstructure evolution

Xiaojing Fu (California Institute of Technology)

(MS06-B) Interfacial phenomena across scales

Oral Presentation

The microstructure of snow determines its fundamental properties such as the mechanical strength, reflectivity, or the thermo-hydraulic properties. Snow undergoes continuous microstructural changes due to local gradients in temperature, humidity or curvature, in a process known as snow metamorphism. Dry snow metamorphism occurs at temperature below the melting point where the snow is assumed...

171. Stochastic modeling of reaction at the fluid-solid interface

Tomas Aquino (IDAEA -- CSIC)

(MS06-B) Interfacial phenomena across scales

Oral Presentation

Understanding, quantifying, and predicting biogeochemical reaction rates is a fundamental scientific challenge with broad implications for the characterization and management of the critical zone and beyond. Unlike under the special conditions found in laboratory batch tests, mass transfer limitations are ubiquitous in natural systems, and the resulting incomplete mixing that can dramatically...

49. Pore-Scale Modelling and Simulation of Precipitation and Crystallization in Porous Media: Insights into Clogging Patterns for CO2 Mineral Trapping

Dr Sarah Perez (Heriot-Watt University)

19/05/2025, 13:55

(MS06-B) Interfacial phenomena across scales

Oral Presentation

Understanding reactive microscale flows in porous media is essential for managing the geochemical processes involved in subsurface $CO_2$ storage. These processes, including precipitation, crystallization, and dissolution, contribute to the mineral trapping of injected CO2 and govern the evolution of fluid-mineral interfaces. Bridging these pore-scale phenomena with their large-scale...

35. Modeling nanoparticle-stabilized foam flow in porous media accounting for particle retention and permeability reduction

Ms Tatiana Danelon de Assis (Federal University of Juiz de Fora)

(MS06-B) Interfacial phenomena across scales

Oral Presentation

Nanotechnology has been rapidly growing in various industrial sectors, particularly in subsurface applications such as soil and aquifer remediation, greenhouse carbon storage, and enhanced oil recovery (EOR). An application of nanoparticles with great potential is the stabilization of emulsions and foams, which are used as mobility-control agents to optimize gas flooding. However, retention...

303. Modeling the foam dynamics in heterogeneous porous media

Prof. Grigori Chapiro (Universidade Federal de Juiz de Fora)

(MS06-B) Interfacial phenomena across scales

Oral Presentation

Foam flow in porous media is important in various engineering applications, including soil remediation, carbon dioxide sequestration, and enhanced oil recovery. This study explores the relationship between bubble density and permeability in foam flow models, focusing on how different approaches capture foam formation in highly permeable regions. We compare two mechanistic models numerically....

583. Unstable dynamics of two-phase displacement in porous media associated with hydrogen storage

Yu Qiu (Stanford University)

19/05/2025, 14:40

(MS06-B) Interfacial phenomena across scales

Oral Presentation

Hydrogen storage in saline aquifers offers a promising large-scale, long-term strategy for renewable energy storage. Compared to conventional CO2 geological storage, hydrogen injection introduces unique challenges due to its ultra-low viscosity and density, high rock reactivity, and microbial driven consumption [1]. In this work, we set aside bio-geo-chemical reactions to focus on the...

123. Statistical scaling of nanoscale spatially heterogeneous dissolution rates at mineral-water interfaces

Chiara Recalcati

19/05/2025, 17:10

(MS06-B) Interfacial phenomena across scales

Oral Presentation

Dissolution and precipitation processes taking place at the interface between water and the solid matrix of the host porous medium are key drivers for chemical weathering of minerals in subsurface environments. Direct high-resolution imaging of mineral substrates subject to dissolution/ precipitation document that these reactions are driven by local mechanistic phenomena originating at natural...

317. Boundaries regulates convection, dispersion and solid-liquid phase change in porous media under Rayleigh-Darcy convection

Dr Ke Xu (Peking University)

19/05/2025, 17:40

(MS06-B) Interfacial phenomena across scales

Oral Presentation

Rayleigh-Darcy (R-D) convection emerges when fluid density at the top is higher than that at the bottom in a porous stratum. This density mismatch may be induced by geothermal gradient or concentration contrast during CO2 or mineral dissolution. R-D convection largely determines the vertical heat and mass transfer, and may significantly reshape the porous matrix.

Here we introduce our...

378. Quantifying Voidage Distributions in Fluidised Bed Reactors Using CFD-DEM Simulations

Mr Jesus Gonzalez (Queen Mary University of London (QMUL))

19/05/2025, 17:55

(MS06-B) Interfacial phenomena across scales

Oral Presentation

In drinking water purification operations, liquid-solid fluidised (LSF) bed reactors are often used, for example in seeded crystallization softening processes (1). Fluidised beds can be considered as dynamic porous media with fascinating spatio-temporal behaviours (1). Usually, LSF systems are considered to be homogeneous under moderate superficial fluid velocities. However, recent...

101. Relating oil-water two-phase flow pore-scale phenomenon to Darcy-scale constitutive relations

Avinoam Rabinovich (Tel Aviv University)

20/05/2025, 09:05

(MS06-B) Interfacial phenomena across scales

Oral Presentation

Multiphase flow in porous media on large (Darcy) scales is conventionally modelled by constitutive relations: relative permeability and capillary pressure functions. These are typically obtained experimentally and are specific for a given porous medium and flowing phases under certain conditions. The approach, although widely used, is still under scrutiny. One of the fundamental challenges of...

(MS06-B) Interfacial phenomena across scales

Oral Presentation

Recently, reflection interference fringe (RIF) and transmission fringe techniques (TIF) have been introduced to investigate the origin of far-field interference fringe formation and to determine a droplet’s contact angle and thickness. In this study, an integrated analysis of the interference fringe (IF) technique is conducted by varying the schematics, including configuration...

(MS06-B) Interfacial phenomena across scales

Oral Presentation

Phase nucleation on substrates with different geometries arises in many important industrial processes such as condensation, crystal growth, and desalination [1]. The nucleation behavior on planar or spherical surfaces has been accurately elucidated [2-3]. However, on the surfaces with complex geometries, the dependence of the energy barrier for forming a critical nucleus on the geometry and...
