Abstract

We have experimentally studied the process of microexplosive fragmentation of two-component (diesel fuel–water) liquid droplets heated in a high-temperature gas medium. The experiment involved a group of 10–30 droplets falling down in a tubular muffle furnace. The delay times of microexplosion were studied and it was established that integral characteristics of the process significantly depend on the relative arrangement of droplets in the group. Limiting distances between droplets (within an average initial droplet radius of 8–10) are established for which the microexplosion characteristics are close to those observed in experiments with single droplets.

一组不均匀燃料液滴的微炸碎裂

摘要

我们已经通过实验研究了在高温气体介质中加热的两组分（柴油-水）液滴的微爆炸破碎过程。实验涉及一组10–30的液滴在管状马弗炉中掉落。研究了微爆炸的延迟时间，并确定该过程的整体特征明显取决于该组中液滴的相对排列。建立了液滴之间的极限距离（平均初始液滴半径为8-10），其微爆炸特性接近于单液​​滴实验中观察到的极限值。
