Research news on Nonlinear dynamics in fluids

Nonlinear dynamics in fluids is a research area focused on the analysis and prediction of fluid flows governed by nonlinear partial differential equations, such as the Navier–Stokes and Euler equations. It investigates phenomena including hydrodynamic instabilities, transition to turbulence, coherent structures, pattern formation, and spatiotemporal chaos across a wide range of Reynolds numbers. Methods commonly involve asymptotic analysis, bifurcation theory, dynamical systems approaches, numerical simulation, and experimental visualization. The field aims to characterize attractors, energy cascades, and multiscale interactions in laminar, transitional, and turbulent regimes, informing modeling, control, and reduced-order descriptions of complex fluid behavior in both natural and engineered systems.

Driven electrolytes are agile and active at the nanoscale

Technologies for energy storage as well as biological systems such as the network of neurons in the brain depend on driven electrolytes that are traveling in an electric field due to their electrical charges. This concept ...

Scientists observe the first 'quantum rain'

In the Quantum Mixtures Lab of the National Institute of Optics (Cnr-Ino), a team of researchers from Cnr, the University of Florence and the European Laboratory for Non-linear Spectroscopy (LENS) observed the phenomenon ...
