摘要：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.
