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 …

Basic fluid equations are the main ingredient in the development of theories of Rayleigh–
Taylor buoyancy-induced instability. Turbulence arises in the late stage of the instability …

Tuning transport properties through the manipulation of elementary structures has achieved
great success in many areas, such as condensed matter physics. However, the ability to …

Direct numerical simulations of a liquid electrolyte with polymer additives demonstrate that
viscoelasticity promotes an earlier transition from steady to unsteady electroconvective flow …

We study, using direct numerical simulations, the effect of geometrical confinement on heat
transport and flow structure in Rayleigh-Bénard convection in fluids with different Prandtl …

The interaction of flexible polymers with fluid flows leads to a number of intriguing
