Swirl flow of refrigerant vapour in a bubble absorber helps to improve absorption rates. Bubble dynamics significantly impact the heat and mass transfer rates of the bubble absorber. Experiments are conducted on a glass bubble absorber with swirl entry of air into the water to understand bubble hydrodynamic characteristics. A cavity-type swirl generator is used to create swirl motion to air bubbles. A high-speed photography approach is used to visualize the bubble behaviour under the impact of a swirl. The study examines different water flow configurations, such as still, co-current, and countercurrent relative to air, and investigates the effects of airflow and water flow rates on bubble properties like departure diameter and time, etc. Subsequently, the experiments are extended to a bubble absorber working with R134a-DMF to observe bubble behaviour during mass transfer using two high-speed cameras.
