The Effect of Multi Nozzles on the Characteristics of Annular Jet Pump

다중노즐을 이용한 환형 제트 펌프의 성능에 관한 연구

Experimental and theoretical researches about jet pump have been carried out by many researchers. Jet pump can be used for the transportation of solid materials, farm produce, and fishes. It is the purpose of this paper to seek optimal multi nozzle shape of the annular jet pump. Experiments were done for several jet nozzle areas, jet nozzle arrays and jet nozzle lengths. Water was used for both the primary fluid and secondary fluid. The efficiency curves for the annular jet pump having multi nozzles are presented in this paper.
