Zusammenfassung: | <jats:p>The atomization process of liquid droplet is an important stage in the fluid movement process in the jet exhausting atomization nozzle. This stage is directly influenced on the diameter and desperation of water droplet. Today two-dimensional model is often used in the most common simulation framework. But the atomization process in nozzle is usually happened in the three-dimensional model, so the results are not quite agreed with the practice. In this paper, a new three-dimensional model was proposed to study the mechanism of the atomization process. After applying the VOF method and turbulent model in CFD software Fluent, a numerical simulation was performed to analyze the mechanism of atomization process and some related factors affecting the atomization. Results indicated that the shapes of atomization were accorded with experimental investigations. According to the results, the necessity of further characteristic parameters on the atomization process was analyzed.</jats:p> |
