Abstract

As a result of experimental consideration on flow characteristics in a hydrogen lift pump (electrolytically-generated hydroden bubble-lift pump) and air lift pump, the following findings are clarified. A hydrogen lift pump begins pumping up of the liquid at a smaller gas volume flow rate aerated than an air lift pump. For the same gas volume flow rate aerated, the liquid flow rate in the hydrogen lift pump is larger than that in the air lift pump. This is under the assumption that the flow pattern of liquid and gas in a riser pipe of the hydrogen lift pump is bubbly flow which consists of bubbles with diameters of about 0.5 mm. On the other hand, the flow pattern in the air lift pump is slug flow with large bubbles. Namely, in bubbly flow much liquid is accompanied by small bubbles, as small bubbles have small slip velocity on liquid and gas phases.
