Abstract

Characteristics of gas-droplet flow created by spraying a liquid using an advanced pneumatic nozzle for suspension fuel were studied experimentally. The measurements were made using the shadow photography method. On the example of water, the disperse composition of the gas-droplet flow, jet expansion angle, and flow structure stability were determined for different regimes. It was shown that most droplets were less than 10 \(\mu\)m in size. The disperse composition of the flow remained unchanged for a wide range of operating parameters. The nozzle designed generates droplets of a size sufficient for efficient combustion of suspension fuel under real conditions.

使用气动喷嘴喷涂液体作为悬浮燃料

摘要

实验研究了通过使用先进的气动喷嘴对悬浮燃料喷射液体而产生的液滴流的特性。使用阴影摄影方法进行测量。以水为例,确定了不同工况下液滴流的分散成分,射流膨胀角和流结构稳定性。结果表明,大部分微滴均小于10  \(\亩\)米的尺寸。在广泛的操作参数范围内,流的分散成分保持不变。设计的喷嘴产生的液滴尺寸足以在实际条件下有效燃烧悬浮燃料。
