Air-Water Flow in Hydraulic Jumps on Macro-Roughness
, 2016 Hydraulic jumps are highly complex three dimensional flows with strong energy dissipation and air bubble entrainment associated with intense mixing. To date turbulence and air-water flow observations in hydraulic jumps have been limited to smooth rectangular channels.

Planar Solid‐State Nanopores Toward Scalable Nanofluidic Integration Based on CMOS Technology
Advanced Engineering Materials, EarlyView.We present a scalable silicon‐based fabrication strategy for planar solid‐state nanopores to enable their integration with complex nanofluidic systems. Prototype devices demonstrate normal voltage‐current characteristics, good noise performance, and appreciable streaming currents. Our CMOS‐compatible fabrication process offers precise geometric control

Advective Diffusion of Air Bubbles in Turbulent Water Flows [PDF]
, 2008 In turbulent free-surface flows, strong interactions between turbulent waters and the atmosphere may lead to some air bubble entrainment. The entrained air is advected within the bulk of the flow and the air-water mixing give a whitish appearance to the ...
