In order to analyze and control the anomalous phenomena of turbomachinery, the following studies were conducted by separate teams of different universities.Nagoya University Team : The stall in a draft tube of a low-head water turbine was observed. By introducing an inlet swirl the stall could be suppressed and the optimum strength of the swirl was clarified for different types of swirl generators.Yokohama National University Team : Using shallow slits grooved radially in the wall of vaneless diffuser of a centrifugal pump, the stall could be suppressed for a wide range of flow rate.Kyushu Institute of Technology Team : The pressure pulsation caused by the interference between the rotating and stationary blades was clarified experimentally and theoretically.Mie University Team : The effects of the vertically uneven wind velocity on the pressure distribution on the blades were examined experimentally.Kyushu University Team : The relation between the cavitation surge and blade angle of a pump inducer was clarified experimentally and the prediction method was obtained.Osaka University Team : To suppress the non-periodical vibration of a pump inducer caused by the rotating cavitation, the behavior of blades with alternatively different chord lengths was found to be effective.

为了分析和控制涡轮机械的异常现象，不同大学的不同团队进行了以下研究。 名古屋大学团队：观察低水头水轮机尾水管失速。通过引入入口涡流，可以抑制失速，并明确了不同类型涡流发生器的最佳涡流强度。横滨国立大学团队：利用在离心泵无叶扩压器壁上径向开槽的浅狭缝，可以在较宽的流量范围内抑制失速。九州工业大学团队：由旋转叶片和固定叶片之间的干涉引起的压力脉动被 三重大学团队：通过实验研究垂直不均匀风速对叶片上压力分布的影响。九州大学团队：通过实验阐明空化喘振与泵诱导轮叶片角度之间的关系，并获得预测方法。大阪大学团队：为了抑制旋转空化引起的泵诱导轮的非周期振动， 发现具有不同弦长的叶片的行为是有效的。
