Self-Ignition Model of a Hydrogen Air Mixture

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 process rate during induction. A simplified analytical descript...

Description
Summary: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 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 self-ignition limits from the adiabatic heating rate of the mixture is described.
