Abstract
The current fluid dynamics video, showcases the hydrodynamic be-haviour of bubbles in a viscous media as compared with a medium oflesser viscosity. The level of mixing that the two-phase gas in liquidflow causes is the parameter of interest
The hyperref package is used to make links to the videos.Two sample videos are Video 1 and Video 2.Detailed understanding of two-phase gas liquid flows is imperative fordeveloping efficient multi-phase reactors through precise control of mixingand reaction kinetics. The bubble column is a good apparatus for elemen-tary studies of such flows. In the current study experiments are conductedto assess the effect of liquid viscosity on flow dynamics inside a bubble col-umn. Corn oil and water are used as the continuous media, and air wasthe dispersed media. The objective of this effort is to use the results for aqualitative validation of the numerical simulations.1 a r X i v : . [ phy s i c s . f l u - dyn ] O c tt
