Prediction of droplet size distribution in sprays of prefilming air ...

WebGurubaran et al. (2008) studied extensively a prefilming hollow cone airblast atomizer in a strong swirling air flow field and measured the spray cone angle, spray patternation, … WebAdvanced prefilming airblast atomizers are widely used for low emission combustors since they deliver a fine spray almost independently of the fuel flow rate. The droplet spectrum produced by this type of atomizer results from the aerodynamic forces at the atomizer edge and from the fuel properties prior to the film disintegration. unshackled manchester
