Abstract
The simulation of the internal flow of a kind of high-pressure swirl injector was carried out with multiphase and cavitation models basing on the movement mesh. The spray was also simulated with the result of the internal flow simulation. The result of spray simulation was compared with experimental results. In addition, the effect on the internal flow which comes from the swirl flutes, the parts for generating the swirl flow, was investigated. It is shown that the amount and configuration of swirl flutes have crucial influence on the swirl velocity and cavitation of the internal flow.
