Abstract: The velocity of bubbles in polydisperse bubbly flow in an inclined flat channel has been studied for various values of the Reynolds number (4500–22700) and gas volume fraction. The diameter of gas bubbles was studied using the shadow photography. It has been shown that for small values of the Reynolds number, the relative velocity of the bubbles is higher. For small gas volume fraction, 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.
Keywords: flat channel, gas-liquid flow, bubbles, gas volume fraction, liquid velocity.
