Self-ignition model of a hydrogen air mixture
O. V. Shults All-Russian Scientific Research Institute of Technical Physics (VNIITF), Snezhinsk, 456770, Russia
Abstract:
A numerical analysis of self-ignition of a hydrogen–air–water vapor mixture at different initial pressures is carried out. The results of this analysis are used to make a shortened list of reactions that make the largest contribution to the process rate during induction. A simplified analytical description of the system state before self-ignition, which makes it possible to calculate the thermal power and adiabatic heating rate of the system is presented. A method for estimating the autoignition limits from the adiabatic heating rate of the mixture is described.
Keywords:
autoignition, ignition limits, hydrogen, kinetic mechanism, radicals, mathematical model.
