A Reduced Reaction Model for Combustion of n-Pentanol

n-Pentanol, a promising biofuel, can reduce greenhouse gas emissions while remaining compatible with internal combustion engines.We present a reduced kinetic mechanism comprising 66 species and 292 reactions that captures both high-and low-temperature ignition and flame propagation dynamics for this fuel.The mechanism, developed by integrating a detailed n-pentanol sub-mechanism with the San Diego mechanism and applying sensitivity and steady-state approximations criteria as reduction strategies, accurately reproduces key phenomena, including the negative temperature coefficient behavior (NTC).Validation against experimental data for ignition delay times, laminar flame speeds, and speciation measurements in a jet-stirred reactor confirms its predictive capability across a wide range of conditions.
