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.

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 ...
