Study on the effect of equivalence ratio on laminar combustion velocity of ABE with different component contents

Abstract Through the methods of spherical propagation flame test and one-dimensional planar flame numerical simulation, the combustion characteristics of premixed laminar flow of acetone-n-butanol-ethanol (ABE) fuel with different volume ratios at 0.1MPa and 298K were studied. The results show that with the increase of the equivalence ratio, the laminar combustion velocity of the ABE mixture with different component contents increases first and then decreases, and the maximum value was obtained near the equivalence ratio of 1.1.
