Detailed numerical simulations of Diesel liquid jet sprays have been conducted to elucidate the liquid atomization mechanisms. The obtained flow field is very complicated, but the spray behavior can be understood physically. The jet head formation leads to vortex shedding and subsequent atomization from the head edge. The liquid core surface is also unstable due to gas boundary layer instability and atomization also occurs from here. The final process of droplet generation from a ligament is basically the same as the past research results, and can be explained by the capillary wave destabilization. Such findings can be used for droplet modeling for practical-scale simulations.
