We report the development of a novel measurement system designed to measure bubble properties in bubble curtains (i.e. planar bubble plumes) in situ alongside acoustical measurements. Our approach is based on electrical, contact-based needl...
Quantifying Brownian motion in the presence of simple shear flow with particle diffusometry [0.03%]
在简单剪切流中用颗粒扩散计测量布朗运动

Dong Hoon Lee et al.
Particle diffusometry, a technology derived from particle image velocimetry, quantifies the Brownian motion of particles suspended in a quiescent solution by computing the diffusion coefficient. Particle diffusometry has been used for patho...
