Turbulent flows are characterized by the non-linear cascades of energy and other inviscid
invariants across a huge range of scales, from where they are injected to where they are …

Many fluid-dynamical systems met in nature are quasi-two-dimensional: they are
constrained to evolve in approximately two dimensions with little or no variation along the …

Amphibious robots can undertake various tasks in terrestrial and aquatic environments for
their superior environmental compatibility. However, the existing amphibious robots usually …

We study the generation of 2D turbulence in Faraday waves by investigating the creation of
spatially periodic vortices in this system. Measurements that couple a diffusing light imaging …

We investigate experimentally three-dimensional (3D) hydrodynamic turbulence at scales
larger than the forcing scale. We manage to perform a scale separation between the forcing …

The statistical properties of turbulence differ in an essential way from those of systems in or
near thermal equilibrium because of the flux of energy between vastly different scales at …

We demonstrate that waves excited on a fluid surface produce local surface rotation owing
to hydrodynamic nonlinearity. We examine theoretically the effect and obtain an explicit …

The control of matter motion at liquid–gas interfaces opens an opportunity to create two-
dimensional materials with remotely tunable properties. In analogy with optical lattices used …

The ability to send a wave to fetch an object from a distance would find a broad range of
applications. Quasi-standing Faraday waves on water create horizontal vortices,, yet it is not …

Transport of mass, heat and momentum in turbulent flows by far exceeds that in stable
laminar fluid motions. As turbulence is a state of a flow dominated by a hierarchy of scales, it …
