Three non-conventional convergent-divergent diesel nozzles are compared.
- class="label">•
The nozzle with higher convergence-divergence level shows the higher mass flow and momentum flux.
- class="label">•
The nozzle with higher convergence-divergence level exhibits similar effective velocity than the nozzle with lower level.
- class="label">•
The nozzle with higher convergence-divergence level is more prone to cavitate.
- class="label">•
Better mixing process is expected for the nozzle with highest convergence-divergence level.
