概要

• 論文の詳細を見る

• In order to obtain wider and better performances of an axial-flow pump, the suction performances must be improved. Three impellers having different solidities and blade sections were tested to study the overall-and suction-performances and to observe the cavitation conditions inside the impellers. The additional head loss due to cavitation and the head rise ratio have been shown as the function of the product of cavitation parameter by solidity. The cavitation zone parameter has been illustrated as the pressure distribution on the blade surface. The suction performance may be estimated from it.
