风洞实验室喷雾飘移试验

Wind Tunnel Spraying Drift Measurements

飘移性是衡量喷雾质量的重要标志之一。风洞试验能够有效地控制喷雾条件，从而可对环境因素和使用参数对飘移性的影响进行更为系统的研究。该文通过对不同类型喷头的测试，分析了不同因素对飘移性的影响程度和趋势，并对飘移雾滴在空间的分布状态进行了研究。

Drift potential is one of the most important factors affecting spraying quality. Wind tunnel can provide a well controlled environment in which drift measurements could be made over a range of wind speeds and spraying conditions. Based on the measurements on four types of nozzles, the extent and trend of effects of several variables on drift potential was analyzed and the spatial distribution states of the drift droplets atomized by these four types of nozzles were described in this paper.
