Fluid Dynamic in Bubble Columns with Heat Exchanger Internals [PDF]
Engineering and Technology Journal, 2014 The effects of vertical cooling internals on the gas hydrodynamics was studied in gas-liquid system (bubble columns) for column diameters, 15 and 30 cm in the absence and presence of internals (the % occluded area by internals 5, 10, and 20%).

CFD Analysis of Phase Holdup Behaviour in a Gas-Liquid Bubble Column
Journal of Applied Science & Process Engineering, 2021 Experimental works on bubble column hydrodynamic are normally carried out on a laboratory scale less than 0.3 m with holes number less than 10. In this paper, we discuss several approaches to bubble column scale-up, relying on variables of parameters ...
