Some Characteristics of Fuel Sprays from Open Nozzles [PDF]

open access: yes
The penetration and cone-angle of fuel sprays from open nozzles were recorded with the NACA Spray Photography Equipment. The results show that for injection systems in which the rate of pressure rise at the discharge orifice is high, open nozzles give ...
