Dear Colleagues,

Flow and transport processes in porous media are pervasive in natural and engineered systems. Examples include geological storage of carbon dioxide and nuclear waste, exploitation of conventional and unconventional oil and gas, fate and transport of underground contaminants, degradation of concrete and building materials, fuel cells and batteries, solidification of metallic materials, and bio-filtration devices. A better understanding of these processes is critical to managing improved production of earth’s energy resources and safe disposal of energy-related waste, and to improving the efficiency and durability of engineered systems. However, this is a challenging problem for theoretical analysis, experimental study, and numerical modeling as it involves multiple coupled transport and interfacial processes interacting with complex morphology of natural and man-made porous media over multiple length and time scales. With the rapid advancement of computers and computational methods, numerical modeling has become an essential tool for the analysis of fluid flow and transport processes in porous media.

This Special Issue is dedicated to demonstrating recent advances in modeling fluid flow and related physicochemical transport and interfacial processes in natural or engineered porous materials. These processes include single and multiphase flow, transport of heat and mass, and chemical reactions occurring in the pore space or at the fluid-solid interfaces. Papers may report on original research, discuss methodological aspects, review the current state of the art, or offer perspectives on future prospects.

Specific methods and fields of applications include, but are not limited to:

• Single or multi-continuum models
• Pore-network models
• Conventional computational fluid dynamics methods
• Lattice Boltzmann methods
• Particle methods (molecular dynamics, Monte Carlo methods, dissipative particle dynamics, smoothed particle hydrodynamics)
• Ground water flow
• Geological CO₂ sequestration
• Underground contaminant transport and remediation
• Conventional and unconventional hydrocarbon recovery
• Flow and transport in energy storage and conversion devices (fuel cells, batteries, fixed/fluidized bed reactors, micro power plants)
• Fluid flow and heat transfer in metal foam
• Organic compounds emission processes in porous building materials
• Prediction of physical properties of porous materials
