Kinetics of chemical ionization in shock waves: II. Kinetic model of ionization in methane oxidation

A kinetic model is suggested for chemical ionization in methane combustion. The model is based on the view that the primary ionization event in combustion is the associative ionization reaction CH + O ⇆ CHO + + e − . The results of numerical calculations of the ionization kinetics provide a qualitat...

Summary:A kinetic model is suggested for chemical ionization in methane combustion. The model is based on the view that the primary ionization event in combustion is the associative ionization reaction CH + O ⇆ CHO + + e − . The results of numerical calculations of the ionization kinetics provide a qualitative description for the time variation of the electron concentration. The calculated dependences of the characteristic times, ionization rate, and electron yield on temperature and on the initial methane concentration fit the respective experimental dependences well.
