Experimental study of bubble-drag interaction in a Taylor-Couette flow [PDF]

open access: yes, 2013
This study is an experimental investigation of the interactions between the bubbles, the coherent motion and the viscous drag in a Taylor Couette flow, for the outer cylinder at rest. The cylinder radius ratio is 0.9.

Application of the double optic probe technique to distorted tumbling bubbles in aqueous or organic liquid [PDF]

open access: yes, 2005
The optic probe technique is widely used to investigate bubble reactors. To derive values of bubble local velocities and bubble local sizes, a specific signal treatment is usually applied under severe assumptions for bubble path and shape.

Numerical simulation of bubble dispersion in turbulent Taylor-Couette flow [PDF]

open access: yes, 2014
We investigate bubble dispersion in turbulent Taylor-Couette flow. The aim of this study is to describe the main mechanisms yielding preferential bubble accumulation in near-wall structures of the flow.

Lorenz Curves, Size Classification, and Dimensions of Bubble Size Distributions

open access: yesEntropy, 2009
Lorenz curves of bubble size distributions and their Gini coefficients characterize demixing processes. Through a systematic size classification, bubble size histograms are generated and investigated concerning their statistical entropy.

Effect of Electrolyte Concentration on Bubble Size and Gas-Liquid Interfacial Area in Bubble Column

open access: yesTikrit Journal of Engineering Sciences, 2005
The optimum conditions of bubble column would be the ones that enhance mass transfer and this is accomplished by maximizing gas-liquid interfacial area. In the present work the effect of electrolyte concentration (aqueous solution of sodium chloride NaCl

Numerical Study on Rising Behavior of Single Bubble in Petal-shaped Rod Bundle Channel

open access: yesYuanzineng kexue jishu, 2023
Bubble behavior has a significant impact on the characteristics of two-phase flow and heat transfer. To investigate the dynamics of bubbles in a petal-shaped rod bundle channel, the behavior of bubbles in static water in the rod bundle channel was ...

Surface heat transfer due to sliding bubble motion [PDF]

open access: yes, 2009
The presence of a rising bubble in a fluid can greatly enhance heat transfer from adjacent heated surfaces such as in shell and tube heat exchangers and chemical reactors.

Mitigation of underwater explosion effects by bubble curtains : experiments and modelling [PDF]

open access: yes, 2014
Mine fields and UneXploded Ordnances (UXO) become a danger regarding maritime activities. Since UXOs are strongly affected by marine corrosion after decades, they cannot be handled safely.
