摘要

The effects of increasing the jet expansion angle, decreasing droplet sizes, and forming a bimodal spectrum of droplets in atomizing superheated liquid by a spray atomizer are discussed. Condensation is adopted to be the mechanism governing the formation of a smaller-size fraction, and atomization enhanced by superheating is adopted to be the mechanism governing the formation of a larger-size fraction. Formulas for calculating the droplet diameter and the jet expansion angle are obtained. It is demonstrated that the calculated and experimentally determined droplet sizes are in satisfactory agreement with each other.
