Abstract
Alkylated cycloalkanes are vital components in gasoline, aviation, and diesel fuels; however, their combustion chemistry has been less investigated compared to other hydrocarbon classes. In this work, the combustion kinetics of n-p ropylcyclohexane ( n- Pch) was studied across a range of experiments including pressurized flow reactor (PFR), jet stirred reactor (JSR), shock tube (ST), and rapid compression machine (RCM). These experiments cover a wide range of conditions spanning low to intermediate to high temperatures, low to high pressures at lean to rich equivalence ratios. Stable intermediate species were measured in PFR over a temperature range of 550-850 K, pressure of 8.0 bar, equivalence ratio ( phi) of 0.27, and constant residence time of 120 ms. The JSR was utilized to measure the speciation during oxidation of n- Pch at phi of 0.5-2.0, at atmospheric pressure, and across temperature range of 550-800 K. Ignition delay times (IDTs) for n- Pch were measured in the RCM and ST at temperatures ranging from 650 to 1200 K, at pressures of 20 and 40 bar, at phi = 0 . 5 , 1 . 0 . In addition, a comprehensive detailed chemical kinetic model was developed and validated against the measured experimental data. The new kinetic model, coupled with the breadth of data from various experiments, provides an improved understanding of n- Pch combustion. (c) 2021 The Author(s).
