Abstract

The mechanisms of primary break-up of a jet produced by a Pressure Swirl Atomizer for aircraft use is investigated. A grid study has been done together with the inlet boundary adopted to setup the simulation. The simulations are undertaken using the in-house multiphase code FS3D based on the volume of Fluid (VOF) method. All simulations were carried out on the Cray XC40 at the High Performance Computing Center Stuttgart (HLRS).
