Impact of surface tension, viscosity and flow rate on air bubble formation in aqueous methanol at temperatures 293.15, 303.15 and 313.15 K

Abstract

This study investigates the effects of temperature, surface tension, and viscosity on air bubble production in an aqueous methanol solution. Experiments are conducted at three temperatures (293.15, 303.15 and 313.15 K) and varying flow rates. It is shown that lower temperatures and higher surface tension and viscosity lead to smaller bubbles, while increased temperatures promote larger and more frequent bubble formation. Flow rate variations significantly influence the bubble dynamics, with higher flow rates generating more bubbles. Research findings have implications for optimizing gas-liquid interactions in industrial processes.
