Abstract
Break-up and atomization characteristics of JetA liquid fuel were investigated numerically. The results have been compared to various experimental results to evaluate the accuracy of the numerical model. The CFD code ANSYS-CFX 12.0 was used to carry out the steady state analysis at different time scales. A comparison between the atomization characteristics of a pressure jet atomizer and an air-blast atomizer is shown. By employing a Lagrangian particle tracking method to track the path of the liquid particles, the liquid jet/spray phenomena was studied in light of low and high back pressure environments. The 'BLOB' primary atomization model and the Cascade Atomization and Breakup model 'CAB' which is an extension of the Enhanced Taylor Analogy Breakup model 'ETAB' was incorporated for analyzing the secondary breakup. Parameters taken into consideration were the JetA liquid particle traveling time and distance, Sauter Mean Diameter, Weber number, JetA Liquid Average Velocity and the turbulence kinetic energy.
