An experimental study was conducted to determine the effects of nozzle orifice size and operating parameters on the cone angle of a liquid fuel spray injected into a gaseous environment. High fuel pressures in the range 55 to 130 MPa and background gas density ranging from atmospheric to 40 kg/m 3 were used in the study. The results show the spray cone angle to depend on the orifice dimensions as well as on the operating conditions such as the injection velocity and the background gas density. A correlation is derived to predict spray cone angles in terms of Reynolds and Weber numbers. The predicted results are shown to agree well with the experimental findings of other investigators.
