Flame Propagation In Premixed Mixtures Of Liquid Biofuels

Abstract

There is a great potential for biofuels in automotive applications because they show advantages in mitigating greenhouse-gases, improving air quality, and reducing our dependence of fossil fuels. Ketones are new class of biofuels produced from endophytic conversion of cellulose. 2,4-Dimethyl-3-pentanone (DIPK) is a promising ketone for automotive applications. In this study, the laminar burning velocity (LBV) of DIPK was investigated in a spherical combustion chamber at initial T=120°C and various initial pressures using two ignition (laser and spark) techniques. Both constant pressure and constant volume approaches were used to derive the LBV values. The flame stability was assessed based on Markstein length, linear, and nonlinear extrapolation methods. The extended LBV values along one isentrope in constant volume method, helps in obtaining LBV values in a high pressure and temperature environment similar to automotive engines. Current data can be compared to the predictions of recent DIPK chemical kinetic mechanisms.
