Paper Abstract

The present paper aims to investigate the atomization process of a liquid that turns into very small drops due to high pressures. Liquid drops in motion encounter a coaxial gas flow of different speed and temperature. It is of interest to study the way the liquid jet first breaks into droplets in the vicinity of the nozzle, and then how the droplet atomization process occurs. The evolution of droplet size and velocity throughout the flow must be determined. It is necessary to make a connection between the mechanisms which start the atomization process and the corresponding environmental conditions. The influences of average droplet diameter, gas velocity and liquid surface tensions in the atomization process are analyzed. It was hypothesized that Rayleigh-Taylor instability occurs as the dominant mechanism for the formation of primary droplets. The present work seeks to eliminate the empirical correlations adopted for the atomization, and to determine droplet size by analytical calculation, based on the working environment parameters.
