✦ Synopsis

A recent paper by Vandooren et al. [ll presents interesting experimental results on the relative properties of methane flames with oxygen or nitrous oxide as oxidant and argon as diluent in each case. The flames are subatmospheric laminar flat flames, which as such are truly one dimensional with propagation dependent on one space coordinate only. Concentration profiles of stable (e.g., CO) and highly reactive (e.g., CH,) intermediates as well as temperature profiles are presented.

The present author wishes to comment on the discussion given of the burning velocities (flame velocities) with the two oxidants.
