A Mathematical Model for The Performance of Solar Heating Driven Bubble Pumps

Khaled Elshawesh, Khairy Agha, Elhadi Dekam.


Abstract
A mathematical model of the bubble pump is established by employing the governing equations; the continuity, momentum and energy equations. Th model was used to evaluate the performance of the pump under diffrent geometrical and operational conditions. Diffrent parameters including the pump tube diameter, the pumping head, and solar heating input were considered in the analysis. Th flw rates of both phases (liquid and vapor) were predicted for each set of parameters. Methanol was used as the working flid. The performance is presented for a number of diffrent scenarios. Th flw was found to be increased with both larger diameters and low static heads, while it has a roughly sine curve with the heat input. A set of results show that for a tube diameter of 10 mm and pumping head of 450 mm, increasing the heat input from 300 W to 500 W increases the mass flw rate of vapor from 0.04 kg/sec to 0.08 kg/sec, while the liquid flow increases from 0.075 kg/sec to 0.22 kg/sec, respectively. Generally, the results of this study were found to be in fair agreement with published results.

Key words: Bubble pump, two phase flow, liftng liquids with thermal heating
