(a) Integrated intensity versus number of acquired frames for a snake-like scan of a water jet of initial diameter 100 µm with a flow rate of 2.235 ml min−1 referred to region I. (b) Integrated intensity versus number of acquired frames for the same scan, but calculated for region II. (c) Amplitude of the Gaussian fitting of the integrated intensity versus distance from the nozzle for the water jet for regions I and II. The points are fitted with a sigmoid curve (shown in the picture) whose position of half value is considered as the jet break-up length. |
