Water droplet bouncing dynamics
Nano Energy, 2021Abstract Droplet bouncing on surfaces has long been observed in nature and industry, which is rather intriguing and instructive for related technology development. Recent decades have witnessed significant progress on the mechanism exploring, device development, and application demonstrations.

Dynamical states in liquid water
Journal of Molecular Liquids, 1993Abstract In this paper we present a review of several investigations performed on H 2 O in normal and supercooled phase, by different light scattering techniques. The obtained results give indications of the growth of some extended structure at low temperature and in the supercooled liquid phase. Such phenomenon reflects in the behaviour of a “ slow ”

Slow Dynamics in Supercooled Water
MRS Proceedings, 1996ABSTRACTWe review some recent results on the self-dynamics in deep supercooled (simulated) water, obtained by analyzing very long Molecular Dynamics simulations. We discuss the possibility of interpreting the observed slowing down of the dynamics in terms of Mode Coupling Theory for supercooled liquids and, at the same time, of associating the ...

Light- and heavy-water dynamics
Physica B: Condensed Matter, 2000Abstract We show first results of an analysis of the dynamics of water as observed by neutron scattering, based on a model common to both isotopic forms, H2O and D2O. Using incoherent scattering results from H2O, and the liquid structure factor of D2O, we show that within the framework of an approximation of decoupled motions, the H2O and D2O spectra

Water dynamics in DMSO–water mixture
Physica B: Condensed Matter, 2000Abstract We study water dynamics in the eutectic DMSO–water mixture by incoherent quasielastic neutron scattering. Water individual motions are modelled by uncoupled whole-molecule translations and rotations around the center of mass. We determine water self-diffusion coefficients, residence times for jump diffusion and rotational relaxation times ...

Chemistry and Technology of Fuels and Oils, 2021
The usual numerical simulation of the oil-water two-phase water cone is difficult to popularize because of its complicated method and the large amount of calculations and data involved. Based on the assumption that oil is supplied horizontally at the outer radius of the oil zone, some simplified water cone calculation methods ignoring the lifting ...

Collective Dynamical Properties of Liquid Water
Physical Review Letters, 1988A theoretical and computer simulation analysis suggests that two collective modes can propagate in liquid water for wave vectors $kg0.64$ ${\mathrm{\AA{}}}^{\ensuremath{-}1}$. The low-frequency mode (ordinary sound) turns out to be associated with the oxygen density fluctuations, whereas the hydrogen density fluctuations are found to be governed by ...

Phosphorus Dynamics in Lake Water
Science, 1973An exchange mechanism exists in lake water between phosphate and plankton, but the excretion of an organic phosphorus compound by the plankton is also a significant process. It results in the extracellular formation of a colloidal substance, and most of the nonparticulate phosphorus in lake water is in this form.

Journal of Fluid Mechanics, 2018
Diving induces large pressure during water entry accompanied by the creation of cavity and water splash ejected from the free water surface. To minimize impact forces, divers streamline their shape at impact. Here, we investigate the impact forces and splash evolution of wedges entering water as a function of the wedge opening angle.
