Abstract

Experiments in expanding spherical flame were carried out to investigate unstretched laminar burning velocities by adding ethylene mole fractions of 0.1, 0.2, and 0.3 to methane-air mixtures at room temperature and elevated pressures up to 4 atm. Our experimental methodology was validated through comparison of a variety of flame radius ranges from previous experimental studies and three kinds of extrapolation model with numerical ones in methane-air premixed flames. Based on them, also the wrinkling of methane/air with increase of ethylene addition is examined experimentally and theoretically under increased pressure at various equivalence ratios.
