ABSTRACT:
There is disclosed a novel nozzle assembly comprised of a tapered liquid passageway and a tapered gas passageway of diminishing cross-sectional areas disposed at an angle of from 0.degree. to 90.degree. to one another meeting at the enlarged end of a gas-liquid mixture passageway of diminishing cross-sectional area to an outlet end thereof. Accordingly, separate streams of a pressured gas and a pressurized liquid are introduced into the respective gas and liquid conduits whereby the gas and liquid are accelerated to a high velocity while minimizing velocity head loss and admixed at converging angles to achieve immediate high forward velocity and thus gas-liquid dispersion with the resulting gas-liquid mixture being subsequently accelerated with minimum pressure losses to achieve further gas-liquid dispersion and thus, microbubble production from controlled volumes of gas and liquid. For producing sprays, there is used like nozzle assembly, except that the liquid passageway need not be tapered and without high liquid velocity requirements.
