Liquid atomization is an important process which found interest in several engineering applications such as aerospace propulsion systems, automotive engines, food processing, aerosols and ink-jet printing. Its numerical simulation allows to investigate physical processes of the atomization because our understanding on physical mechanisms of such phenomena is still not sucient. Our investigation group is doing its rst steps in this research area and we report in this work our early results using two dierent approaches. On one hand a typical Eulerian collocated nite volume and on the other hand a Lagrangian based Particle Finite Element Method (PFEM) using both a volume of fluid (VOF) two phase flow model to capture the atomization phenomenon. The final target of this research is the improvement of less detailed methodologies to be applicable in the internal combustion engine simulation using the results obtained here with an almost direct numerical simulation.
