Abstract
The three-dimensional, two-phase flow dynamics and underlying physics in an open-type liquid swirl injector are investigated using numerical simulations. The basis for this study is a validated multiphase flow solver, interFoam, in OpenFOAM. Turbulence closure is achieved by means of LES with a one-equation eddy-viscosity turbulence model. A volume-of-fluid method is used for tracking the interface between the gas and liquid phases. The detailed spatio-temporal evolution of the flow field is explored systematically, including the liquid surface wave motion and liquid film characteristics within the injector, the helical air core, and the formation and atomization of the liquid spray cone downstream of the injector. The spectral content of the pressure field is also examined, to reveal the characteristic frequencies and feedback mechanisms of gas-liquid interactions.
