Experimental measurement of bubble breakup in a jet bubbling reactor
AIChE Journal, 2020AbstractThe bubble breakups in a jet bubbling reactor are captured using a high‐speed camera and the velocity field is measured by particle image velocimetry. Two typical breakup patterns, jet breakup and jet‐vortex breakup are observed. The breakup time interval of the jet‐vortex breakup is two orders of magnitude higher than the jet breakup.

Bubble Breakup and Coalescence in a Plunging Liquid Jet Bubble Column
The Canadian Journal of Chemical Engineering, 2003AbstractIn this study the bubble size distribution and energy dissipation rate are measured in a plunging liquid jet bubble column. The maximum stable bubble diameter in the mixing zone was successfully predicted based on Weber number analysis. A Pareto analysis indicated that the coalescence of bubbles principally occurred as a binary process.

Leidenfrost droplet jet engine by bubble ejection
Journal of Colloid and Interface Science, 2023Despite the flourishing studies of Leidenfrost droplet motion in its boiling regime, the droplet motion across different boiling regimes has rarely been focused on, where bubbles are generated at the solid-liquid interface. These bubbles are probable to dramatically alter the dynamics of Leidenfrost droplets, creating some intriguing phenomena of ...

Jets in quiescent bubbles caused by a nearby oscillating bubble
Journal of Applied Physics, 2012An oscillating bubble near another (stationary) bubble can give rise to interesting interactions. Such a nonequilibrium (oscillating) bubble can create a jet in a smaller nearby (initially stationary) bubble as demonstrated in this study both experimentally and numerically.

Abstract Air–water bubbly jets are studied experimentally in a relatively large water tank with a gas volume fraction, Co, of up to 80% and nozzle Reynolds number, Re, ranging from 3500 to 17,700. Measurements of bubble properties and mean axial water velocity are obtained and two groups of experiments are identified, one with relatively uniform ...

Characterization of the bubble swarm trajectory in a jet bubbling reactor
AIChE Journal, 2019AbstractThe bubble swarm trajectory in the jet bubbling reactor is measured through the bubble image velocimetry (BIV) technique. The result shows that the bubble swarm rises straightly when the jet Reynolds number is lower than 7,000. However, when the jet Reynolds number exceeds 14,000, the bubble swarm exhibits vortex‐like motion, and the bubble ...

Drops, jets and bubbles occur in many different technological and scientifically relevant situations and, thus, have been the subject of a great deal of theoretical and experimental work. In the six lectures presented here, I have focused on the equilibria and dynamics of captive drops (or liquid bridges), the thermocapillary migration of drops. In the

This paper is concerned with some nonlinear free surface flows. Some are problems that Joe and I solved over the last 25 years. Others may not be joint but were inspired by Joe’s ideas and enthusiasm for research. Still some others are problems Joe and I started working on and that we hope to solve soon.

Bubble and liquid flow characteristics in a vertical bubbling jet
International Journal of Multiphase Flow, 1995Summary: A vertical bubbling jet was formed in a cylindrical water bath by injecting air from a centric single-hole nozzle. Bubble characteristics, such as gas holdup (void fraction), bubble frequency, mean bubble rising velocity, mean chord length, were measured using a two-needle electro-resistivity probe.
