Abstract

The multi-holes orifice plate are simple hydrodynamic devices which can be used for intensification of liquid-liquid heterogeneous micro-mixture for preparing bio-diesel or emulsified diesel. In this study,a flow visualization experiment system with a transparent hydrodynamic cavitation reactor was setup to investigate the cavitation in the orifice plate and the outlet of the orifice plate. The effect of upstream pressure and cavitation number were investigated. The experimental results show that with the increasing of upstream pressure the caviation occurs in the orifice plate and the outlet of the orifice plate which are correspond with the numerical results.The numerical results also show that cavitation cloud shedding are the source of the cavitation of the outlet of the orifice plate.
