Experimental study of instability characteristics in pump turbines
Journal of Hydraulic Research, 2018Experiments in a medium specific-speed pump turbine scaled model are performed to investigate instability characteristics in pump mode, namely the head-drop phenomena. Two different head-drops are captured on a pump performance curve. This paper presents

A device which brings about an exchange of energy between a mechanical system and a fluid medium is a fluid machine. If the machine is driven mechanically to work on the fluid system and thereby transform mechanical energy into ‘fluid’ energy it is referred to as a pump.

After years of development and preclinical testing, clinical trials of the MicroMed DeBakey VAD began in November 1998 in Europe and in June 2000 in the United States. As of August 2000, 44 patients in Europe and 3 patients in the United States have undergone implantation with the MicroMed DeBakey VAD.

For the purpose of optimizing pump turbines installed in pumped storage plants with regard to efficiency, cavitation, and excavation costs, a method of computation has been devised which includes a new system of determining type number and impeller outside diameter. An example employing data applicable to a modern pump turbine—Rodund 2(Austria)—reveals
