Many experiments, following the report (1), were carried out to investigate the effect of various factors on the performance of bubble production of an ejector type gas-nozzle built as a trial. As a result, (1) the optimum design standards for the development of the ejector type gas-nozzle were determined, and (2) it became clear that the Weber number We of liquid-jet, when plotted on logarithmic graph paper, changed linearly with the Reynolds number Re of the aspirated gas flow according to the relation We=bRem. Then, (3) the expression for predicting the ζ, the ratio of the aspirated gas flow Qg to the liquid-jet flow QL, was derived from the above We-Re relation.
