A Correlation for the Burning Velocity of Methane–Air Mixtures at High Pressures and Temperatures

Abstract

A formulation for the burning velocity of methane–air mixtures was developed over a range of equivalence ratios at temperatures and pressures high enough to cover conditions encountered in a typical operating spark ignition engine using the experimental data of Babkin and Kozachenko [1] . An example involving the use of such data in a diagnostic program to yield information about the characteristics of flame propagation in an engine fueled with methane is shown.
