Numerical Simulation Analysis on Upstream Flow Field of Low-Pressure Swirl Nozzle
The three-dimensional flow physical model of internal flow field of low-pressure swirl nozzle was established with optimized swirl core parameters.By means of adjusting diameter and length-diameter ratio of the nozzle,the upstream flow field of nozzle was simulated by using Fluent software and compared with the experimental data to investigate the effects of the diameter and length-diameter ratio to the atomization property and atomizing angle.The research results indicate that axial velocity decreases with the increase of the diameter in the same length-diameter ratio,and the atomizing angle increases with the decrease of the length-diameter ratio and increases with the increase of the diameter.These are consistent with the test results.
