摘要
针对含能液体的特点,用不稳定波理论,建立了射流破碎的简化模型,模型中考虑了射流初始破碎、液滴之间的碰撞聚合和破碎。经过数值计算,得到了不同喷嘴结构条件下,HY911射流雾化液滴的 Sauter 平均直径分布并与实验结果进行了分析比较。
A Simplified model for primary breakup of energetic liquid jets is established using unstable wave theory,Initial atomization,later atomization,collision and aggregation among droplets are consid- ered during the numerical simulation.The distribution of droplet sauter mean diameter under vary nozzle structure conditions is obtained by numerical calculation.Results are in good agreement with experimen- tal data.
