Shock Tube Ignition Studies Of Advanced Biofuels

Ignition delay times for diisopropyl ketone, an advanced biofuel candidate, were measured behind reflected shockwaves. Current experiments were performed for temperatures in the range of 1100-1600 K and for pressures between 1 and 6 atm. Equivalence ratios for all of the experiments were between 0.5 and 2.0. The ignition delay measurements were compared to the predictions of recent kinetic mechanisms. An emprical correlation for the ignition delay time was created to describe the effects of the differnet parameters and the activation energy for the fuel was determined to be 28196 cal/mol
