Effect of NO2 addition on flame dynamics and chemical kinetics of near-limit n-dodecane cool and warm diffusion flames

Theoretical Kinetic Study on Hydrogen Abstraction Reactions from n-Pentane by NO2

“…Alkanes are one of the important components of traditional transportation fuels, accounting for ∼50% by mass in jet fuels and ∼70% in diesel fuel. , A better comprehensive understanding of the kinetic mechanism of alkanes with NOx is helpful to clarify the autoignition process of transportation fuels in the application of EGR technology. In recent years, the interaction of hydrocarbon (RH)/NOx chemistry has attracted researchers’ attention by means of experimental and kinetic modeling studies. − ,− Prior studies have shown that NOx has both promoting − and inhibiting effects − on the reactivity of hydrocarbon fuels. However, the presence of NOx has been recognized as an ignition-promoting effect by Glarborg et al They found that NO 2 plays a role in promoting chain-branching by abstracting H atom to form HONO or HNO 2 , and subsequently, they both decompose to OH and NO.…”
