The hydraulic characterization of the nozzles under ‘‘Spray A”
conditions shows that, when the measured nozzle outlet geometry
is accounted for, all the studied nozzles behave reasonably
similarly. Although both nozzle typologies used have similar
nominal flow capacity in terms of Bosch flow number and
despite outlet diameters of ‘‘Spray C” nozzles being larger than
‘‘Spray D” ones, the stationary mass flow rate is higher in ‘‘Spray
D” ones due to non-cavitating operation under all tested
conditions.
