尿素选择性催化还原（SCR）系统需要通过雾化促进尿素水溶液的蒸发，以提高氮氧化物的净化效率。本研究提出了一种创新的雾化方法，该方法对喷雾液滴的撞击壁面进行了表面纹理处理。通过对撞击液滴的高质量可视化验证了该方法中的雾化机理。
The promoting evaporation of urea-water solution by atomization is required to improve the purification efficiency of NOx for the urea SCR system. This study proposed an innovative method of atomization which processed a surface texture to the impingement walls of the spray droplet. The atomization mechanism in this method was verified by the high qualitative visualization of the impingement droplets.
