报告简介：

Inverse diffusion flames (IDFs) have been used in the promising autothermal reforming (ATR) method for hydrogen production from natural gas. However, soot formation in ATR is a main concern since it gives rise to catalyst degradation. IDFs display distinct differences in sooting characteristics from normal diffusion flames (NDFs) and have been the subject of several recent numerical and experimental studies. This talk focuses on the flame structure and sooting characteristics of IDFs as revealed from numerical simulation using detailed reaction mechanism and soot model. The simulated flames include ethylene IDFs at atmospheric pressure and CO2-diluted CH4 IDFs at elevated pressures. The differences in relative importance of inception, surface growth, and oxidation and the pressure effect on soot formation between NDFs and IDFs are highlighted.
