Laminar flame speeds of hydrocarbon + air mixtures with hydrogen addition☆
G. Yu,Chung K. Law,Chuanjia Wu +2 more
TL;DR: In this article, the laminar flame speeds of methane + air and propane + air mixtures, with and without the addition of stoichiometrically small amounts of hydrogen, have been determined by first measuring the flame speeds with stretch and then linearly extrapolating these values to zero stretch.
