本文发展了考虑可压缩效应的双向耦合三维涡方法,将涡方法拓展至蒸发性喷雾的模拟.离散相液滴的运动采用拉格朗日方法跟踪,采用考虑了吹风效应和对流效应的N-G-R-M模型计算其传热传质.针对文献中的丙酮喷雾实验开展数值模拟,获得喷雾涡量场发展过程及涡量分布规律,并与实验数据进行对比,液滴直径的空间分布与实验结果吻合良好,本文模型可预测出喷雾液滴的平均寿命.“,”In present paper,a three-dimensional vortex method concerning two-way coupling and compressible effect was developed for the evaporating spray simulation.The vorticity change and vortex convection was simulated,and the gas velocity field was solved by the dual-potential method,while droplets were tracked by Lagrange method.This method was implemented to simulate the acetone spray,and simulated droplets diameter profiles achieved good agreement with experimental data.The evolution and the spatial distribution of vorticity field in acetone spray were concluded.The profiles of droplet life time were obtained for the guidance of industrial applications.
