This paper focuses on the statistical analysis of a droplet population produced by a pressure-atomized jet spray, laying in the second-wind-induced regime, far behind the nozzle. The droplet size and axial velocity derived from droplet tracking velocimetry measurements are shown to follow bimodal distributions and their modeling is tackled in the framework of turbulence and of combustion applications, respectively. In addition, the existence of subsets of droplets showing specific behaviors is brought to light from the analysis of the experimental droplet-size-velocity joint probability distribution function (PDF). Such subsets can be precisely defined using the properties of the size and axialvelocity distributions. Finally, the trend of the joint PDF is depicted due to a quadratic relationship which is derived in the context of combustion and shown to work here as well, far behind the nozzle.
