Studies on the Steam Jet Pumps for Lifting Unsaturated Water
Chemical engineering, 1955 蒸汽缶給水用インゼクタにては,ノズルからの噴出蒸汽量の中で約8%が,ディフューザを通過しなければ送出圧力が使用蒸汽圧力より高くなり得ないことが実験結果を用いて計算された。多量の不飽和水を吸入するエゼクタについては約10%の蒸汽がディフューザ喉部に残ることが必要であり,この値が特性を左右しているわけである。この数値を用いると,不飽和水を吸入する蒸汽噴射ポンプの設計は従来よりも合理的になると思われる。その簡単な計算方法を導いた。

Rotating Stall Region of Water-Jet Pump
Transactions of FAMENA, 2014 There is a rotating stall region, which is the so-called unstable head curve when water jet is operated. This region should be usually avoided because of the risk of instabilities during the pump starting and operation. Experimental and numerical research on the relation between the instability in the head curve and the magnitude of unsteady hydraulic ...
