ジェットポンプに関する研究(第1報) : (原動, 被動流体共に水の場合)

抄録

The author determined the construction of the Jet Pump which makes its effeciency maximum by experiment and theory. The best value of the diameter of nozzle is (0.5∼0.7) d (d=diameter of throat) and varies by the elevation of water to be lifted. The length from the outlet of nozzle to the inlet of throat should be less than 2d, the throat length L should be 2.5d<L<4d. The conical angle at the inlet of diffuser does not affect the efficiency in the range 30°∼50°.
