An experimental study to lift water with a solar-driven bubble pump

Abstract

This study presents an experimental investigation centered on the utilization of a solar bubble pump for lifting water. Experimental tests were conducted to analyze the impact of various design and operational parameters. The results revealed a direct proportionality between the maximum height lifted heat flux. Additionally, the experiments demonstrated that increasing the submergence ratio resulted in a higher mass flow of lifted water. Furthermore, a slight increase in tube diameter, while maintaining a constant heat flux and submergence ratio, led to a 22.47% increase in the flow rate when the diameter was increased from 8 mm to 10.21 mm.
