Abstract

Abstract

In this paper, CFD Fluent was used to carry out a numerical simulation study on the tooth side shear cavitator. The changes in the cavitation between tooth vortex, the volume fraction of cavitation bubbles, and turbulent kinetic energy were analyzed. And the influence of operating parameters, such as rotation speed and processing capacity on the cavitation performance of the cavitator was obtained. The results showed that the vortex in the cavitator was the main way to generate cavitation bubbles. The vortex between the fixed teeth and the movable teeth was generated by the fluid impacting the wall surface and swirling with the injected fluid. However, the vortex between the tooth flanks was formed by the mechanical shear of the two flanks. It meant that sufficient mechanical shearing and shearing area could make the vortex distribution between tooth flanks the widest, indicating that increasing mechanical shearing could effectively induce the formation of cavitation bubbles. The collapse of cavitation bubbles caused the turbulent kinetic energy at the sharp edge of the tooth tip to increase, and the turbulent kinetic energy increased with the increase in rotational speed. It meant that the cavitator could not only increase the content of cavitation bubbles, but also increased the collapse rate of cavitation bubbles, which effectively improved the cavitation performance. However, the volume fraction of cavitation bubbles decreased with the increase of the processing volume, so as the cavitation performance.
