Cylinder water entry on a perturbed water surface
Journal of Fluid Mechanics, 2023 The perturbations existing on a breaking wavefront can be a potential explanation for the slamming pressure variability in wave impacts. Here, we investigate the effect of these perturbations by forced vertical slamming of a two-dimensional circular cylinder with constant downward velocity on standing waves. Through experimental modelling and numerical

Experimental Investigation on Motion Hydrodynamics of Water Entry for Inclined Cylinders
Shanghai Jiaotong Daxue xuebao, 2021 Experiments of vertical water entry for a cylinder with different inclined angles are performed at a low Froude number to investigate the cavity evolution and hydrodynamics. Unique phenomena of double cavities and separated cavity are observed.

Thermodynamics of Water Entry in Aquaporins [PDF]
Biophysical Journal, 2014 Permeation of water across cell membranes is facilitated by highly efficient, selective water channels called aquaporins. While a large number of experimental and computational studies over the last decade have provided great details about the mechanisms of permeation and selectivity in these proteins, some of the fundamental aspects of the mechanism ...

The water entry of decelerating spheres [PDF]
Physics of Fluids, 2010 We present the results of a combined experimental and theoretical investigation of the vertical impact of low-density spheres on a water surface. Particular attention is given to characterizing the sphere dynamics and the influence of its deceleration on the shape of the resulting air cavity.

Gender mainstreaming in water reuse: guidelines for planners, investors, project designers and operators [PDF]
, 2023 Gender equity is essential for the success of water reuse projects in the Middle East and North Africa (MENA), yet women remain underrepresented in decision-making, employment, and planning processes.
