乙炔/空气层流预混火焰中氢气添加对碳烟颗粒生成的影响
Influence of hydrogen addition on soot formation in laminar acetylene/air premixed flames
摘要
Abstract
The mathematical model of soot dynamical process was built in laminar one-dimensional premixed flames, and the interpolated method of moments was used to solve the mathematical model coupled with the detailed chemical kinetic model with the soot precursors. The computation platform was established based on Fortran language, and the effect of hydrogen addition on soot formation in laminar acetylene/air premixed flames was investigated by numerical simulation. The results show that the addition of hydrogen to the C2H2/air premixed flames can slow down the formation of PAHs, inhibit particles nucleation rate, coagulation rate and surface growth rate due to the thermal effect, dilution effect and direct chemically inhibiting effect, which finally decreases the soot formation.关键词
