Large Eddy Simulations (LES) of an evaporating spray jet is performed using an explicit filtering approach for carrier phase equations. Droplets are treated as representative point particles without any modeling of particle sub-grid-scale (SGS) evolution. The simulation of a recent benchmark dilute acetone spray experiment showed that close quantitative agreement could be obtained of the downstream self-preserving turbulent state. Several other simulations are performed to understand the effect of inflow fluctuation level, evaporation and droplet size on the relaxation to the self-preserving state.
