This study was performed to investigate the effects of L/D ratio of the nozzle on initial development and macroscopic spray behavior of diesel spray to understand the formation process of spray cone angle. Near-field and ...

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 ...

In this study, spray characteristics of n-heptane and propane were investigated under different injection pressure using various imaging techniques such as Mie-scattering, DBI (diffuse back-illumination), and Schlieren ...

Sulfur-Iodine cycle (SI cycle)은 요오드와 황을 첨가하여 최종적으로 물을 열화학적으로 분해하여 산소와 수소를 생산하는 공정으로 황산분해, 요오드화 수소 분해, 분젠반응 등 세가지 반응들로 이루어져 있다. 분젠 반응은 두가지 공정 중간에 존재하므로 두 반응에 필요한 화학물을 조달하는 역할로 이에 대한 상분리 및 반응기에 대한 분석이 중요하다. 본 연구에서는 50 L/hr ...

This study was carried out to analyze the spray characteristics as a function of the operating parameters of urea injector used in Urea-SCR system of passenger diesel vehicle. Spray visualization and PDPA experiment were ...
