Study on Two-Phase Mixing Inside Flow Focusing/Blurring Nozzle by Gray Distribution Analysis Method

The application prospect of a flow focusing/blurring nozzle is broad but research on gas-liquid inside the not comprehensive. mixing difficult to study by visualization experiment, so this paper proposes or gray scale level distribution experimental images. results show that increase air rate beneficial two-phase nozzle, while influence water rate, tube hole distance (the between inner and outlet) orifice diameter opposite. inertia force weaker than under different parameters, effect similar small relatively weak. In addition, analysis field in zone shows stable focusing mode. blurring mode, has radial stability axial pulsation. transition unstable, close
