2608 新型マイクロバブル発生装置の性能と応用性に関する研究 : 水への酸素の溶存特性(S44-1 マイクロ気泡・粒子,S44 マイクロ・ナノフルイディクス)  [in Japanese] 2608 Optimum design of a New Micro-bubble Generator and its applications to industries : Performance of Dissolved Oxygen into water  [in Japanese]

In this study, experiments have been conducted in order to improve the performance and the efficiency of Sadatomi's micro-bubble generator. Time-variation in dissolved oxygen in water at different discharged rates of air and water have been measured by changing water depth to the generator. From the variation data, K_La (Volumetric Mass Transfer Coefficient) and E_A (Oxygen Absorption Efficiency) were calculated. In addition, the effect of salty on K_La and E_A have been studied.
