To better understand how turbulent flow structures develop within shear-thinning suspensions (STSs), we investigate the behavior of a shear layer forming within an STS downstream of a sudden expansion with an expansion ratio of 0.5. Specifi...
Simultaneous measurements of velocity, oxygen concentration, and deformed interface position in an air-water channel using PIV and LIF [0.03%]

Oxygen transfer across a deforming air-water interface is studied using a synergy of particle image velocimetry and laser-induced fluorescence (LIF). Such approaches have previously been limited to flat interfaces. We develop simultaneous m...

Over the past decade, there has been a tremendously increased interest in understanding the neurophysiology of cerebrospinal fluid (CSF) flow, which plays a crucial role in clearing metabolic waste from the brain. This growing interest was ...
Heterodyne background-oriented schlieren for the measurement of thermoacoustic oscillations in flames [0.03%]
异质背景定向schlieren法在火焰热声振荡测量中的应用

In aircraft engines, thermoacoustic oscillations in the combustion chamber contribute significantly to noise emissions, which, like all other emissions, must be drastically reduced. Thermoacoustic oscillations are not only a concern, they c...
The influence of water turbulence on surface deformations and the gas transfer rate across an air-water interface [0.03%]
水体扰动对水面形变及气液界面气体传输速率的影响研究

Traumatic brain injury (TBI) poses a major public health challenge. No proven therapies for the condition exist so protective equipment that prevents or mitigates these injuries plays a critical role in minimizing the societal burden of thi...
Jetting bubbles observed by x-ray holography at a free-electron laser: internal structure and the effect of non-axisymmetric boundary conditions [0.03%]
自由电子激光下x射线全息观测到的喷气泡：内部结构和非轴对称边界条件的影响
Juan M Rosselló,Hannes P Hoeppe,Max Koch et al.
Juan M Rosselló et al.
In this work, we study the jetting dynamics of individual cavitation bubbles using x-ray holographic imaging and high-speed optical shadowgraphy. The bubbles are induced by a focused infrared laser pulse in water near the surface of a flat,...
