The effects of atomizer dimensions and operating conditions o n spray cone angle and velocity coefficient are examined. A theoretical approach is adopted to determine the liquid film thickness in the final discharge orifice and to relate this thickness to cone angle and velocity coefficient. The calculated results are shown to compare satisfactorily with the experimental data reported in the literature. Equations are presented for predicting cone angle and velocity coefficient in terms of the nozzle pressure differential and the nozzle constant K, which is defined as the ratio of inlet ports area to the product of discharge orifice diameter and swirl chamber diameter. Introduction The processes of atomization of liquid-fuel fired combustion and evaporation systems. Normal vortex. The outlet f r o m the swirl chamber is the final orifice, and the rotating liquid flows through this orifice under b o t h axial and radial forces to emerge from the atomizer in the form of a hollow conical sheet. The actual cone angle is determined by the relative magnitude of the radial and axial components of velocity at exit. Downstream of the atomizer the liquid sheet rapidly disintegrates into ligaments and then drops. Although the basic
