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.
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 ...

The development of humans and other animals unfolds gradually over time, with cells taking on specific roles and functions via a process called cell fate determination. The fate of individual cells, or in other words, what ...
The ocean is saturated with microplastics. While we know the location of the great garbage patches, where plastic particles may accumulate below the ocean surface remains unknown. The vastness of the ocean means particle ...
