건설기계용 Urea-SCR 시스템의 촉매전단에서 암모니아 균질도 해석 및 DeNOx 성능에 관한 연구

In this study, the spray atomization characteristics of urea injector used in SCR system for construction machinery was analyzed, and the uniformity index at the front of mixer and NOx conversion efficiency were evaluated through numerical analysis. Spray visualization and droplet size/velocity meas...
