The pursuit of next-generation internal combustion engines with higher thermal efficiencies and lower greenhouse gas emissions has motivated fundamental research to explore currently unexploited combustion chemistry pathways. In recent years, researchers have focused on low temperature combustion technologies which have demonstrated potential to satisfy environmental regulations that the automotive sector is required to meet. Low temperature chemistry (LTC) engine technologies include strategies such as homogeneous charge compression ignition (HCCI), reactivity-controlled compression ignition (RCCI), partially premixed compression ignition (PPCI), and spark-assisted compression ignition (SACI), and have received great attention. However, LTC fuel oxidation is still not well-understood despite its importance in combustion phenomena such as engine knock. This dissertation advances the understanding of LTC, and the cool flames formed from LTC, through experiments and simulations of combustion phenomena that incorporate both complex LTC kinetics and transport interactions. Fundamental cool flame properties such as propagation speed and LTC-derived CH2O structure in premixed and nonpremixed flames are measured experimentally to provide novel insights into cool flame characteristics and simulation targets for model development. Insights from experiments and modeling are applied to the simulation of cool flames formed from droplet combustion in microgravity, such as those discovered aboard the International Space Station (ISS). The outcomes of this dissertation provide new insights into LTC and cool flames in engine-relevant applications, and the data and analyses developed in this work can aid in the future development and refinement of LTC kinetics models.
