Abstract
Mixing and transport processes are the key issues in studying two-phase bubbly flow in a bubble column. Especially, the bubble-induced liquid phase mixing is a complex function of void fraction distribution, gas phase velocity and so on. To study the characteristics of the mixing induced by the bubbles, we have designed a rectangular bubble column where the mean void fractions ranging from 0.006 to 0.075%. High-speed shadowgraphy technique is used to measure the different gas phase properties such as bubble size, void fraction, and bubble velocity. To measure the mixing, on the other hand, we have used a direct visualization method with low diffusive buoyant dye. The results reveal both qualitative and quantitative measurements.
