| 内容記述タイプ | Abstract | |||||
| 内容記述 | It is important for raising the flow rate ratio of air to water that the inter-phase area between air and water should be increased and the local stagnation of water should be prevented. For example, if we give the jet some swirl or use some special nozzles (star crosssection type or multihole type), the characteristics of the ratio will be improved as compared with normal nozzles. The transient drop in the ratio experienced in the low vacuum operation is removed by the swirled jet and long delivery pipe. A semi-empirical expression of the forementioned ratio that is applicable to the region of middle vacuum pressure is deduced from the concept of interphase friction force. Also, as regards optimum jet pressure and transition vacuum pressure, their causes are quantitatively clarified and their experimental values agree considerably well with the calculation. | |||||
