Estimation of overall droplet size distribution from a local droplet size distribution for a jet in crossflow: Experiment and multiphase large eddy simulations

•Experiment and multiphase large eddy simulations (LES) of oil jet in crossflow.•LES was coupled with the population balance model to compute local droplet size.•Maximum energy dissipation rate after 16 pipe diameters distance from the orifice was not sufficient to break the droplets injected at the orifice.•Plume DSD changed slightly after 15 pipe diameters distance from the orifice.•Overall plume DSD can be estimated from the measurement at a single point in the plume.
