Studies on diffuser of mixed flow pump.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1987 For the purpose of improving performance of a mixed flow pump, it is necessary to investigate not only an impeller but also a diffuser. The latter, however, has been investigated scarcely. Thus, in this report, the performance and internal flow of the mixed flow diffuser with vanes were clarified. The following conclusions were mainly derived.

3-D Viscous Flow Analysis of a Mixed Flow Pump Impeller
International Journal of Rotating Machinery, 2001 This paper presents the results of a study using a coarse grid to analyze the flow in the impeller of a mixed flow pump. A commercial computational fluid dynamics code (FLOTRAN) is used to solve the 3-D Reynolds Averaged Navier Stokes equations in a ...

Experimental Study on Cavitation in Mixed-Flow Pump Impellers
Transactions of the Japan Society of Mechanical Engineers, 1963 Several mixed-flow pump impellers were tested in a test pump for the purpose of studying the effects of the number of vanes and the inlet edge shape on their performance and cavitation characteristics. The shockless entry flow rates were obtained from the incipient cavitation conditions and inlet flow deviation angles were found, their degree varying ...

Modelling of vertical shaft of mixed-flow pump [PDF]
Archive of Mechanical Engineering, 2013 Abstract The aim of the work was modelling of shaft and calculation of natural vibration frequencies and critical rotations of a large-size, vertical mixed flow pump of total length l=4866 mm. Equations of motion were determined analytically, and then calculation results were verified by numerical modelling. The difficulty of the problem consisted
