Abstract
The bubble velocity in polydisperse bubbly flow in an inclined flat channel was studied for different Reynolds numbers (4500–22 700) and gas volume fractions. The diameter of gas bubbles was studied using shadow photography. The relative bubble velocity was found to be higher for low Reynolds numbers. For small gas volume fractions, a significant number of bubbles has a small diameter (1 mm), and at high gas flow rates, the bubble diameter increases to 3–5 mm.
