Droplet size distribution inside water flashing jets and corresponding rainout fraction were measured. Mass distribution showed that a few droplets are "large" (> 150 micro m) and count for more than 85 % of the liquid mass in the jet because of their large individual mass. This could be due to incomplete thermal fragmentation. It could explain the rain-out falling near the orifice or pipe exit.
