Atomization is a complex phenomenon, particularly difficult to simulate due to its physicalcharacteristics, such as its long range of scales and discontinuous nature of the interphase . There areseveral alternatives to represent the interphase. The Volume of Fluid (VoF) is a widely adopted tech-nique that employs a phase volume fraction function to distinguish between the fluids involved. Anopen-source implementation is available on the the OpenFoam FVM suite for incompressible immisci-ble flows, called interFoam. This application solves the color function advection equation using HighResolution Schemes limited with a Flux Corrected Transport in conjunction with a compression flux inorder to reduce diffuses errors. The momentum equation is solved applying the PISO algorithm. In thiswork, the solver performance is studied comparing numerical results with experimental data and lineartheory solutions. Dynamic mesh refinement is applied to find a high performance setting for long rangescales flows. Finally, results related to jet atomization are reported.
