摘要

本文研究了采用压缩空气雾化器的喷水系统的喷水质量，该雾化器设计用于向内燃机进气歧管喷水。该系统由一个双缸活塞压缩机组成，用于压缩工作腔中的水气混合物。活塞压缩机通过长通道与雾化器相连。液滴大小是通过阴影摄影法进行自动图像处理测量的。液滴速度场采用 2D-PIV 方法测量。实验结果表明，当空气/水质量比大于 0.46 时，喷射系统的雾化质量较高。萨特平均直径不超过 31.1 微米。

Experimental study of sizes and velocities of the droplets produced by water injection system with compressed-air atomizer into the intake manifold of an internal combustion engine applying the optic methods

The paper studies the quality of water spraying by system with a compressed-air atomizer designed for water injection into the intake manifold of an internal combustion engine. The system consists of a two-cylinder piston compressor providing compression of water-air mixture in the working chambers. The piston compressor has connection to the atomizer through long channels. The droplet sizes were measured through automatic image processing by the Shadow Photography method. The droplet velocity field was measured by 2D-PIV method. Experimental results demonstrated that the injection system offers a high quality of atomization for the air/water mass ratio higher than 0.46. The Sauter mean diameter was no more than 31.1 µm.
