Factors Influencing the Effective Spray Cone Angle of Pressure-Swirl Atomizers
Journal of Engineering for Gas Turbines and Power, 1992The spray cone angles produced by several simplex pressure-swirl nozzles are examined using three liquids whose viscosities range from 0.001 to 0.012 kg/ms (1 to 12 cp). Measurements of both the visible spray cone angle and the effective spray cone angle are carried out over wide ranges of injection pressure and for five different values of the ...

High pressure effervescent atomization: effect of ambient pressure on spray cone angle
Fuel, 2001Abstract Cone angles of sprays formed by a high injection pressure effervescent atomizer were investigated as part of a study concerning the application of effervescent atomization to diesel fuel injection. Spray cone angles were studied in high ambient density environments that simulate conditions inside the combustion chamber of a diesel engine at ...

Analysis and Research on Guiding Cone Angle Parameter of Spray Fan-Pipe [PDF]
International Journal of Fluid Mechanics & Thermal Sciences, 2016 Guiding cone angle is an important parameter in the design of the spray fan, the difference of guiding cone angle has a significant impact on the spray effect and service life of the fan. Based on this, the numerical simulate of fluid-solid coupling for the pan is carried out by using the RNG k-e model, turbulence equations and SIMPLEC algorithm, then ...

Effect of geometric parameters on the spray cone angle in the pressure swirl injector
Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, 2012Spray cone angle affects the droplet distribution after atomization and is one of the main targets of coaxial gas–liquid injector optimization. Experimental measurements and numerical modeling (volume of fluid method) were used to investigate the effects of geometric parameters on the spray cone angle in pressure swirl injectors ...

Application research on digital image technology in the measurement of nozzle spray cone angle
2011 IEEE International Instrumentation and Measurement Technology Conference, 2011Spray cone angle is one of the important performance indexes of motor nozzle. The size of spray cone angle affects the distribution characteristics of fuel in combustion space directly. This paper uses digital image technology to get the binary edge image of spray cone angle through enhancing, edge detecting, and thinning to the spray cone angle image ...
