Abstract Fuel atomization characteristics are important in the performance of gasification and combustion. This work concerns the interaction of two drops in a continuous air jet stream. Morphological classifications of interaction modes have been analyzed using high speed camera. Behaviors of drops group and the isolated drop in the airflow are significantly different. Experimental photos show that there are four main interaction modes, which are coalescence mode, puncture mode, side by side mode and no direct contact mode. Influence of dimensionless distance on drops interaction mode is researched. Then the drops interaction regime map is obtained. The model prediction is in good agreement with the experimental results. The total dimensionless breakup time of puncture mode is the longest, then the coalescence mode, and the third the side by side mode. Results present an evaluation of the role of proximity to other drops in affecting the outcome, which are useful in understanding atomization mechanism and improving simulation model.

连续喷气使袋子破碎状态中两滴的相互作用

摘要 燃料雾化特性对气化和燃烧的性能具有重要影响。这项工作涉及连续空气喷射流中两滴的相互作用。已经使用高速相机分析了交互模式的形态学分类。液滴组和气流中孤立液滴的行为有显着差异。实验照片显示,主要有四种交互模式,即聚结模式、穿刺模式、并排模式和无直接接触模式。研究了无量纲距离对液滴相互作用方式的影响。然后得到液滴相互作用机制图。模型预测与实验结果吻合较好。穿刺模式的总无量纲分裂时间最长,其次是聚结模式,第三个是并排模式。结果评估了与其他液滴的接近程度对结果的影响,这有助于理解雾化机制和改进模拟模型。
