Thermodynamic Properties of Unburned Reactant Mixtures for Different Kind of Fuels
Journal Title: Journal of ETA Maritime Science - Year 2017, Vol 5, Issue 3
Abstract
Accurate estimation of adiabatic flame temperature and combustion product species play a key role in estimating performance and emission characteristics of internal combustion engines. This can be succeeded only with exact knowledge of temperature and thermodynamic properties of the unburned mixture. In this paper, thermodynamic properties of various fuels and fuel-air mixtures are presented. Differences in gas phase and liquid phase properties are discussed. Effect of equivalence ratio and unburned mixture temperature on enthalpy, specific heat and entropy of unburned fuel-air mixtures as well as effect of phase change on adiabatic flame temperature are shown. In order to serve as a recourse tool for researchers of combustion and internal combustion engines, the required polynomial coefficients used in calculation of thermodynamic properties are tabulated in famous NASA format for various important chemical compounds which are commonly used to represent surrogates of diesel, gasoline, Jet-A and many other fuels.
