Interactions in fluids as a research area investigates the microscopic and macroscopic forces and couplings among fluid constituents (molecules, particles, droplets, bubbles, or macromolecules) and their consequences for fluid structure, dynamics, and transport. It encompasses hydrodynamic interactions, intermolecular forces, colloidal and multiphase interactions, and coupling between flow fields and interfaces. The field integrates continuum mechanics, statistical mechanics, and computational fluid dynamics to study phenomena such as non-Newtonian behavior, turbulence modulation, self-assembly in suspensions, and transport in complex or active fluids, with relevance to soft matter physics, chemical engineering, and biological fluid systems.
Understanding water behavior in nanopores is crucial for both science and practical applications. Scientists from City University of Hong Kong (CityU) have revealed the remarkable behavior of water and ice under high pressure ...
