Abstract

In this study a CFD simulation was conducted for better understanding the effect of nozzle geometry on the two phase atomization performance in an effervescent nozzle. Simulations were validated with experimental data that were collected previously. Commercially available Computational Fluid Dynamics (CFD) code (ANSYS-CFX 13) was used for these simulations. Bubble size distributions inside the nozzle were computed using Eulerian-Eulerian two-fluid Population Balance method. Bubble size directly influences the droplet quality in atomization. The CFD results reveal that nozzle geometry has significant effect on bubble size distributions.
