Abstract
An approximation method for evaluation of the caloric equations used in combustion chemistry simulations is described. The method is applied to generate the specific heat, static enthalpy, and Gibb's free energy equations for fuel mixtures of interest to gas turbine engine manufacturers. Liquid phase fuel properties are also derived. The fuels include JP-8, a synthetic fuel, and two fuel blends consisting of a mixture of JP-8 and synthetic fuel. The complete set of property equations for both phases are implemented into a computational fluid dynamics (CFD) flow solver database, and multi-phase, reacting flow simulations of a well-tested liquid-fueled combustor are performed. The simulations are a first step in understanding combustion system performance and operational issues when using alternate fuels, at practical engine operating conditions.
