Abstract
The paper presents a basic investigation for the development of cleaning technology employing an annular nozzle ejector for application to cleaning water supply and air bubble generation. The quantitative flow characteristics of the primary and suction flows, the qualitative visualization behavior of the mixed jet, and the percentage concentration of pesticide residual at different values of the ejector screw pitch were investigated. It was seen that the primary flow rate increased, while the mass ratio decreased with increase in screw pitch. Further, the mixed jet behaved like a buoyancy jet or horizontal bubbly jet, and the residual concentration of pesticide first decreased and then increased with increase in screw pitch.
