Comparison of Jet Fuels by Measurements of Density and Speed of Sound of a Flightline JP-8

September 13, 2010

Author(s)

Stephanie L. Outcalt, Arno R. Laesecke, Karin Brumback

The density of a flightline jet fuel (JP-8) was measured with two vibrating-tube densimeters. The combined range of the data is from 270 K to 470 K with pressures to 40 MPa. The speed of sound in the fuel was measured with a propagation time method at

Analysis of Organometallic Gasoline Additives with the Composition-Explicit Distillation Curve Method

September 9, 2010

Author(s)

Thomas J. Bruno, Evgenii Baibourine

Problems associated with pre-ignition of fuel in a spark ignition engine have been documented for many years, and include poor performance and structural damage. These problems were addressed in the past by adding organometallic additives such as

Extent and Impacts of Hydrocarbon Fuel Compositional Variability for Aerospace Propulsion Systems

July 25, 2010

Author(s)

Thomas J. Bruno, Tim Edwards, Linda M. Shafer, Matthew Billingsley

Kerosene fuels possess physical and chemical properties which make them attractive for aerospace propulsion applications from operational and performance standpoints. However, variation in fuel properties and performance owing to differences in chemical

Evaluation of the Physicochemical Authenticity of Aviation Kerosene Surrogate Mixtures Part I: Analysis of Volatility with the Advanced Distillation Curve

July 19, 2010

Author(s)

Thomas J. Bruno, Beverly L. Smith

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

Evaluation of the Physicochemical Authenticity of Aviation Kerosene Surrogate Mixtures Part II: Analysis and Prediction of Thermophysical Properties

July 19, 2010

Author(s)

Thomas J. Bruno, Marcia L. Huber

In part I of this series of papers, we presented an evaluation strategy that can be applied to surrogate mixtures for finished fuels. This strategy uses the advanced distillation curve approach to evaluate the surrogate in terms of physicochemical

Thermodynamic, Transport, and Chemical Properties of Reference JP-8

Thomas J. Bruno, Marcia L. Huber, Arno R. Laesecke, Eric W. Lemmon, Mark O. McLinden, Stephanie L. Outcalt, Richard A. Perkins, Beverly L. Smith, Jason A. Widegren

This report contains a summary of research conducted to develop a standard or accepted set of thermophysical properties for the aviation kerosene, JP-8. This report is the culmination of a three year effort that included the participation of most of the

The Decomposition and Isomerization of 5-Methylhex-1-yl Radical

July 9, 2010

Author(s)

Iftikhar A. Awan, William S. McGivern, Wing Tsang, Jeffrey A. Manion

The decomposition and isomerization reactions of the 5-methylhex-1-yl radical (1-5MeH) have been studied at temperatures of 889 K to 1064 K and pressures of 1.6 bar to 2.2 bar using the single pulse shock tube technique. The radical of interest was

Software Package to Facilitate the Preparation of Intermediate-Range Fossil Fuel Standards from Certified Reference Materials

June 17, 2010

Author(s)

John L. Molloy, Bruce S. MacDonald, William R. Kelly

A software package has been developed in Visual Basic for Applications to assist analysts in mixing fossil fuel reference materials to produce standards of intermediate concentrations and known uncertainties. Mixing reference materials of similar matrices

Ignition Delay of Fatty Acid Methyl Ester Fuel Droplets: Microgravity Experiments and Detailed Numerical Modeling

June 1, 2010

Author(s)

Anthony J. Marchese, Timothy L. Vaughn, Kenneth Kroenlein, Frederick L. Dryer

Recent optical engine studies have linked increases in NOx emissions from fatty acid methyl ester combustion to differences in the premixed autoignition zone of the diesel fuel jet. In this study, injection (and subsequent ignition) of single, isolated

Surrogate Mixture Models for the Thermophysical Properties of Aviation Fuel Jet-A

May 27, 2010

Author(s)

Marcia L. Huber, Eric W. Lemmon, Thomas J. Bruno

We developed surrogate mixture models to represent the thermophysical properties of two samples of aviation turbine fuel Jet-A. One sample is a composite of numerous batches from a multiple manufacturers and is considered to be a representative fuel. A

Investigating the Unique Properties of Cuphea Derived Biodiesel with the Advanced Distillation Curve Method

May 17, 2010

Author(s)

Tara Lovestead, Bret Windom, Thomas J. Bruno

Currently, there is a desire to extend or enhance petroleum-derived diesel fuel with biodiesel fuel. Biodiesel fuel is a renewable, biomass-derived fluid that is biodegradable, nontoxic, and a better lubricant compared to petroleum-derived diesel fuels. In

Assessment of the Compositional Variability of RP-1 and RP-2 with the Advanced Distillation Curve Approach

May 7, 2010

Author(s)

Bret Windom, Tara Lovestead, Jennifer Riggs, Chris Nickell, Thomas J. Bruno

RP-1 is a long-established hydrocarbon fuel that continues to be widely used as the kerosene component in rocket propulsion systems. The desire in recent years to use rocket motors many times, rather than a single time, has led to reformulations of RP-1

Thermal Decomposition of RP-2 with Stabilizing Additives

May 7, 2010

Author(s)

Jason A. Widegren, Thomas J. Bruno

The thermal decomposition of RP-2 and mixtures of RP-2 with four different additives has been investigated. The mixtures with RP-2 contained one of the following: 5 % /trans/-decahydronaphthalene (decalin); 5 % 1,2,3,4-tetrahydronaphthalene (tetralin); 5 %
