The determination of laminar burning velocity

Abstract

The relevance of data on laminar burning velocities, both from their value to industry and related research areas, and for the validation of theoretical chemical kinetic models, is discussed, as are certain fundamental problems associated with the measurement of this intrinsic property. Various methods which have been used over the years to experimentally determine this property are reviewed and it is concluded that the spherical constant-volume vessel method is both the most versatile and accurate. As a consequence, a summary of the equations required for its correct use are presented. For the purpose of comparing the results of the more reliable techniques, as well as comparing these with recent computer predictions, data on the effects of equivalence ratio, pressure and unburnt gas temperature for methane-air mixtures are reported, as are a number of empirical equations correlating these variables with burning velocity.
