内容記述(抄録等)
Succeeding to the previous report, to ensure effective use of a water-air ejector in aquaculture, this report dealt with the performance of drawing air into water by the mixing shock phenomenon of water-air ejectors with the multi-orifice nozzles.
And the objective of this study was to obtain high drawing air performance and the shortening of the length of working tubes in order to put it to practical use. As the main experimental results, the length of the mixing shock(L_<mix>) was gradually decreased with the increase of the water flow rate. as the result, the working tube length could be able to shorten, keeping the mixing shock phenomenon. Though the rate of drawing air from an air inlet in the nozzles increased with the increase of the cross section area, the increase of the rate of drawing air was not alway the increase of the value of dissoleved oxygen(DO) in water.
