双旋流燃烧室两相喷雾试验和数值研究
Experimental and numerical study on spray atomization in a double-swirler combustor
摘要
Abstract
Using the particle field pulsed laser holography imaging technique,the spatial dis-tribution of droplet diameter in an aeroengine combustor is measured,the atomization process is studied,and the spatial distribution of droplets diameter in the combustor is obtained too.The numerical sprays models of the primary and secondary atomization are established,and a numeri-cal software for the three-dimensional two-phase combustion in the aeroengine combustor is de-veloped.Based on the LISA atomization model and KH-RT breakup model,the primary atomiza-tion process and secondary atomization process in the combustor are simulated numerically, obtaining the distribution of fuel spray droplets in the combustor.The simulation results are compared with experiments.The result indicate that the atomization models developed in this work can properly simulate the whole process of spray atomization under the conditions of high temperature,high pressure and strong swirling in aeroengine combustors.关键词
