Abstract
Detailed measurements of near-nozzle spray formation is essential to better understand and predict the processes involved in diesel fuel atomisation. We previously showed that direct imaging with sub-micron resolution could yield droplet size measurements in the near-nozzle region under non-evaporative conditions, without an arbitrary requirement for droplet sphericity. We now report on progress made with ongoing experimental investigations at elevated pressure and temperature conditions. We conducted tests on a reciprocating rapid compression machine to produce high-resolution panoramas of the liquid spray interface, compared them with high-speed video frames, and measured droplet sizes at key locations. We also studied the size and shape of liquid structures formed during the end of injection, which were found to be significantly larger and slower than those recorded during injection.
