On the relative importance of HONO versus HNO2 in low-temperature combustion

This work investigates whether both HONO and HNO2 are essential in describing the reactivity for NO2-doped ignition experiments or if a strategy could be developed that lumps the two isomers into a single species without adversely affecting the model fidelity. First, the possibility of different product branching fractions is considered; temperature- and pressure-dependent rate constants are computed for H and CH3 addition to the N=O bond in...
