Descriptions
To ensure effective use of a water-air ejector in aquaculture, this paper dealt with the performance of water-air ejectors with the multi-orifice nozzles. And the objective of this study was to put it to practical use. and the principal arrangement of which was shownin Fig. 2.
In the water-air ejector, the water spurted from a multi-orifice nozzle centrally into the mixing tube.
As the experimental result.
1) In the flow phenomenon, it was cleared that the process of mixing of the jets was often completed before the exit section of the working chamber. And the ratio of volume flow(Q_<gs>/Q_w) showed marked increase by the mixing shock phenomenon.
2) The length of mixing tube was gradually decreased with the increase of the water flow rate and was influenced by the size of a orifice.
