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.
A team of scientists have invented a technique to determine the dynamics of microscopic interacting particles by using image recognition to count the number of particles in an imaginary box. By changing the size of the observation ...
In a laboratory set-up simulating the human stomach and intestine, researchers at the University of Amsterdam have explored the fate of plastic nanoparticles during gastrointestinal digestion. In their paper published in ...
