実現性確認試験と性能予測

An advanced micro-bubble generator with a spherical body in a flowing water tube was invented by Sadatomi in 2003. In the present paper, as an industrial application of the micro-bubble generator, a bubble-jet-type air-lift-pump also invented by Sadatomi in 2005 has been presented together with the results of its feasibility test. In the test, effects of particles size, submergence ratio (=the riser length submerged in water divided by the total riser length), and water and air supply rates to the bubble-jet generator on the pump rerformance have been studied. Yoshinaga-Sato model for predicting water and particles discharge rates has been modified and tested against the present experimental data to confirm its validity. The results of such experiments and analyses are reported in this paper.
