Abstract
We present further uses of a theoretical framework based on the integral form of the conservation equations, to gain insight and predictive capabilities for the spray break-up regimes, turbulence effect on drop size, and secondary break-up processes. Quantitatively and qualitatively, the results indicate that the current analysis method can be useful in understanding and predicting various aspects of spray break-up processes. Correct Weber number boundaries for Rayleigh, wind-induced, and atomisation regimes are calculated using a Weber-Reynolds number relationship obtained from first principles. Good agreements with experimental data for turbulence and secondary break-up effects on the drop size are also achieved. It is projected that small modifications of the source terms within this framework can render possible analyses of other important processes, such as swirl sprays and air-blast atomisation.
