Abstract: The vibration in the draft tube of a water turbine is most severe when the turbine is running on part load. This is caused principally by the vortex core of whirling water in the draft ...

Abstract: The most efficient nozzle is generally considered to be that for which the discharge coefficient is nearest unity. Forms and dimensions of the nozzles being equal, the greater the discharge ...

Abstract: Equations of motion for air bubbles in a centrifugal pump impeller were obtained and solved numerically for a flow in a radial-flow-type impeller, and the results were compared with experiments. ...

Abstract: Experimental results concerning the flow pattern and hydraulic resistance in a rotating pipe are described. A fully developed turbulent flow was introduced into a long smooth pipe rotating about ...

Abstract: The performance of an axial-flow pump was investigated under air-admitting conditions and the results were compared with those obtained for radial-flow pumps investigated in our previous studies. ...

Abstract: The pressure recovery and velocity distributions in a two-dimensional rotating curved diffuser have been studied experimentally when even and uneven flows, respectively, were introduced to the ...
