YM Yuk Man Lau

TL;DR: Lau et al. as mentioned in this paper used algebraic closure relations to simulate large-scale gas/liquid contact apparatusses, such as bubble columns, which is essential for the optimization and further development of many bio-chemical and metallurgical processes.

TL;DR: In this article, the overlapping clusters are passed through a watershedding algorithm in order to segment the groups of bubble object areas into individual bubbles, thus leaving only solitary bubbles within an image.

TL;DR: In this article, the authors present an experimental study of the bubble size distribution of a bubbly flow using digital image analysis (DIA), in order to facilitate the image measurement technique a pseudo-2D bubble column is chosen for the experiments.

TL;DR: In this paper, the authors presented a numerical model to predict the bubble size distribution in turbulent bubble flows, where the continuous phase is described by the volume-averaged Navier-Stokes equations, which are solved on an Eulerian grid, whereas the dispersed or bubble phase is treated in a Lagrangian manner, where each individual bubble is tracked throughout the computational domain.

TL;DR: In this article, a comparison between direct numerical simulations (DNS) and experimental data for realistic gas fluidization is made, which reveals a reasonably good agreement with respect to the time-averaged solids motion and the pressure fluctuations.
