Special Issue Information

Dear Colleagues,

This Special Issue focuses on recent advances and developments in the modeling of multiphase flow and reactive transport in porous media. Many fundamental and practical aspects of multiphase flow processes, which are crucial in various energy and environmental applications, are not well understood. For instance, how are the processes controlled by interplay between large-scale flow patterns, such as fingering and local-scale Fickian diffusion, mechanical dispersion, and chemical reaction? How can we incorporate small-scale physical and chemical processes in the pore and core-scale into large-scale multiphase flow and transport models? How does the heterogeneous nature of rock–fluid properties and its uncertainty impact multiphase flow dynamics? What are the implications of thermodynamic changes in fluid properties?

Our goal is to include comprehensive review papers and recent experimental, theoretical, and numerical results, related to the study of complexities in describing multiphase flow dynamics and transport in porous media across a wide range of spatial and temporal scales, including uncertainty analysis and risk assessment of operations. In particular, topics of interest include but are not limited to:

  • Multiphase flow in porous and fractured reservoirs;
  • Geochemistry and reactive transport;
  • Pore-scale processes;
  • Constitutive relations;
  • Enhanced oil/gas recovery;
  • Upscaling flow and transport parameters;
  • Coupled hydraulic, thermal, mechanical, chemical, and biological processes;
  • Advanced modeling framework and methods.

Lauric Acid (LA) phase-change nanocapsules prepared with silver as the shell exhibit excellent energy storage capacity and high thermal conductivity. Still, their functionality could be improved by ensuring uniform morphologies, even the size and thickness of silver particles. In this study, the LA/Ag nanocapsules were prepared under different reductant drop speeds. By adjusting the droplet speed of the reducing agent, the concentration of silver in the solution can be controlled, which affects the nucleation and growth rate of silver particles, thereby influencing the deposition of silver particles on the surface of the core material. The characterization results indicate the successful preparation of high sphericity and uniform-sized LA/Ag nanocapsules. The average diameter of capsules was 117–140 nm, the latent heat was 43.69–47.78 J/g, and the encapsulation efficiency was 80.69–82.53%. As the droplet speed increased, the thickness of the silver shell increased while the encapsulation efficiency decreased. The highest encapsulation efficiency was achieved when the reducing agent dropping speed was 0.03 mL/s. Full article

Solid–liquid organic phase-change micro/nanocapsules are potential candidates for energy storage. Recently, significant progress has been made regarding phase-change micro/nanocapsules in terms of their synthesis, properties, and applications. Extensive research has been conducted to enhance their thermal properties, such as thermal storage capacity, thermal conductivity, and thermal reliability. However, factors that influence the thermal properties of micro/nanocapsules have received little attention. This study presents a comprehensive review of phase-change micro/nanocapsules focusing on their thermal properties and their influencing factors. In addition, the thermal properties of the major solid–liquid organic pure phase-change materials are summarized. Furthermore, common micro/nanoencapsulation methods and their influence on the thermal properties were analyzed. Finally, the potential applications of these phase-change micro/nanocapsules were also investigated. This study was devoted to enhancing the thermal properties of micro/nanocapsules, which play a crucial role in their practical applications. Full article
