Abstract

To better understand the effect of hydrogen and carbon monoxide as additives in the combustion of ethanol/air flames, apparatus was designed and fabricated to produce a flat flame of the said composition. Also this flame setup was numerically analyzed using the CHEMKIN PREMIX software. The limited availability of information in literature on these flames was the motivation for this study. The results of the numerical simulations show that both H2 and CO increase the laminar burning velocity when compared to the pure ethanol flames. Also, H2 addition has greater impact than CO addition. The results also indicate that the flame thickness tends to decrease with both increasing equivalence ratio and increasing additive percentage in the mixture. Furthermore the origin and the end of the inner layer shift to the left with increasing equivalence ratio and as well as additive percentage. Since the amounts of shifts are quite similar, the total inner layer thickness remains constant regardless of varying equivalence ratio or additive percentage.Dept. of Mechanical, Automotive, and Materials Engineering.
