Abstract

Because of the complexities involved in measuring and modeling the performance and properties of finished fuels, the scientific community must often use surrogate mixtures, especially in the absence of consensus standard mixtures. While surrogate mixtures are often formulated based on the ability of a particular mixture to reproduce a particular property, there is a desire to employ surrogate mixtures that are physicochemically authentic. This means that provided the primary purpose is satisfied, researchers are inclined to choose mixtures that have physical and chemical properties appropriate to the finished fuel. In this paper we apply the advanced distillation curve method as a means to evaluate the physicochemical authenticity of surrogate mixtures. While the strategy outlined here can but used for any family of surrogates, we apply it here to surrogate mixtures for Jet-A/JP-8. Mixtures were divided into two groups: simple surrogate mixtures with up to three components, and complex surrogate mixtures with more than three components. We found that the Modified Aachen surrogate (among the simple fluids) and the Schultz surrogate (among the complex fluids) had the best physicochemical authenticity.
