On the breakup frequency of bubbles and droplets in turbulence: a compilation and evaluation of experimental data
Shijie Zhong, Rui Ni
The dispersed phase in liquid-liquid emulsions and air-liquid mixtures can often be fragmented into smaller sizes by the surrounding turbulent carrier phase. The critical parameter…
Deformation and breakup of bubbles and drops in turbulence
Rui Ni
Fragmentation of bubbles and droplets in turbulence produces a dispersed phase spanning a broad range of scales, encompassing everything from droplets in nanoemulsions to centimete…
Folding dynamics and its intermittency in turbulence
Yinghe Qi, Charles Meneveau, Greg Voth +1
Fluid elements deform in turbulence by stretching and folding. In this work, by projecting the material deformation tensor onto the largest stretching direction, the dynamics of fo…
Fragmentation in turbulence by small eddies
Yinghe Qi, Shiyong Tan, Noah Corbitt +3
From air-sea gas exchange, oil pollution, to bioreactors, the ubiquitous fragmentation of bubbles/drops in turbulence has been modelled by relying on the classical Kolmogorov-Hinze…
Simultaneous measurements of deforming Hinze-scale bubbles with surrounding turbulence
Ashik Ullah Mohammad Masuk, Ashwanth K. R. Salibindla, Rui Ni
We experimentally investigate the breakup mechanisms and probability of Hinze-scale bubbles in turbulence. The Hinze scale is defined as the critical bubble size based on the criti…
The Flow Physics of COVID-19
Rajat Mittal, Rui Ni, Jung-Hee Seo
Flow physics plays a key role in nearly every facet of the COVID-19 pandemic. This includes the generation and aerosolization of virus-laden respiratory droplets from a host, its a…
