摘要：

A multi-fluids mixer by Sadatomi and Kawahara [1] is described as well as its performance as a micro-bubble generator for several trial products. In the experiments, air micro-bubble generation rate at water depths up to 3.6 m and the dissolution rates of oxygen in air and carbon dioxide into tap water at 20 degrees C were measured. In the analyses, the micro-bubble generation rate data could be well predicted by Sadatomi et al.'s model [2] by choosing suitable energy loss coefficients needed in the model, and the oxygen dissolution rates in tap water could be well correlated with Kawahara et al.'s model [3]. The detail of the multi-fluid mixer and its practical significances together with a result of experiments and analyses are reported in the present paper. (C) 2012 Elsevier Inc. All rights reserved.
