The objection of this study was to obtain high drawing air performance and the simplifying of the nozzle in order to put it to practical use.
As the main experimental results, the drawing air rate into water was gradually increased with the increase of the water flow rates. Though the rate of drawing air from an air inlet in the nozzle increased with the increase of the cross section of air inlets, the bubbling phenomenon in the nozzle was not alway. As the optimum condition of the nozzle for practical use, the water flow rate, nozzle length, number of injection port, diameter of air inlet and diameter rate of outlet/inside of the nozzle were in the range of 0.4-0.5m3/h, 80-100mm, 3-4mm, 2mm and 0.5 respectively. |
