Summary
Subsurface fluid flow dynamics describes how fluids move through porous rocks and fractured formations, influenced by pressure gradients, permeability, porosity, and multiphase interactions. These processes are central to carbon reduction technologies, where understanding flow behavior enables safe and efficient underground storage of greenhouse gases and supports the transition to carbon-neutral energy systems.
The urgent need for effective climate solutions has driven intensive research into subsurface flow across applications such as geological carbon sequestration, geothermal energy, underground hydrogen storage, and enhanced hydrocarbon recovery with integrated carbon management. In carbon capture and storage (CCS), fluid dynamics governs the injection, migration, and long-term containment of CO₂ in deep formations, relying on mechanisms such as capillary trapping and mineral carbonation. Similarly, geothermal systems harness heat transfer through circulating fluids, while hydrogen storage in porous reservoirs depends on accurate prediction of multiphase flow and geochemical interactions. Enhanced oil recovery processes also integrate CO₂ injection, coupling resource utilization with permanent carbon storage.
This Special Issue highlights advances in multiphase flow behavior, reactive transport, numerical modeling, and innovative sequestration materials, while addressing fault stability, induced seismicity, and storage integrity. Emphasis is placed on computational fluid dynamics, machine learning, and optimized injection strategies. By linking fundamental fluid mechanics with applied carbon management, this collection provides a vital platform to advance research, policy, and practice in global carbon reduction efforts.
