Counterflow ignition and extinction of FACE gasoline fuels

The demand for petroleum-derived gasoline in the transportation sector is on rise. For better knowledge of combustion practical systems, this study presents experimental measurements and numerical prediction autoignition temperatures extinction limits six FACE (fuels advanced engines) fuels counterflow flames. Extinction were measured at atmospheric pressures while experiments carried out high pressures. pressure experiment, fuel stream consists pre-vaporized diluted with nitrogen, a condensed configuration used ignition experiment higher chamber oxidizer pure air. Autoignition tested are nearly same pressure, huge difference observed as increased. Unlike pressures, minor exists fuels. Simulations using recently developed surrogate model. Both multi-component n-heptane/isooctane mixtures surrogates simulations. Overall, consistently more reactive compared mixtures. Transport weighted enthalpy radical index analysis was to explain differences strain rates various
