Understanding Porous Media Flows: Fundamentals, Modeling, and Industrial Applications
Porous media flows involve the movement of fluids through materials with interconnected voids, such as soils, rocks, and engineered filters. These flows are critical in disciplines ranging from groundwater hydrology and petroleum engineering to chemical reactors and environmental remediation.
Modelling Sprays and Surface Films: Fundamentals, Hybrid CFD Approaches, and Industrial Case Studies
From diesel injectors to deodorant aerosols, spray systems are everywhere. When droplets meet a solid wall they may form a thin liquid layer— a surface film—whose dynamics control lubrication, cooling, and coating quality. This article reviews the governing physics, shows how to extend OpenFOAM’s spray solvers with film modelling, and walks through five increasingly complex cases of real industrial relevance.
