Density and Speed of Sound Measurements of Jet A and S-8 Aviation Turbine Fuels

January 27, 2009

Author(s)

Stephanie L. Outcalt, Arno R. Laesecke, Malte B. Freund

The density and speed of sound were measured for three compositions of aviation jet fuel A, and a synthetic fuel (S-8) derived from the Fischer-Tropsch process. Measurements of density and speed of sound were carried out at ambient pressure (83 kPa) with a

Variability of The Rocket Propellants RP-1, RP-2, and TS-5: Application of a Composition- and Enthalpy-Explicit Distillation Curve Method

December 3, 2008

Author(s)

Lisa S. Ott, Amelia B. Hadler, Thomas J. Bruno

We have recently introduced several important improvements in the measurement of distillation curves for complex fluids. This method is a significant improvement over current approaches, featuring a composition-explicit data channel for each distillate

Thermal Decomposition of RP-1, RP-2, and Mixtures of RP-2 With Stabilizing Additives

November 3, 2008

Author(s)

Jason A. Widegren, Thomas J. Bruno

----- FOR POLICY REVIEW ONLY ----- The thermal decomposition of RP-1, RP-2, and mixtures of RP-2 with three different additives has been investigated. The mixtures with RP-2 contained 5% 1,2,3,4-tetrahydronaphthalene (tetralin), 5% 1,2,3,4

Multichannel Decomposition and Isomerization of Octyl Radicals

October 9, 2008

Author(s)

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

The thermal cracking patterns from the decomposition and isomerization of octyl-1 radicals have been determined from the pyrolysis of n-octyl iodide in single pulse shock tube experiments at temperatures in the 850-1000 K range and pressures near 2 bar

Exploring the Oxidative Decompositions of Methyl Esters: Methyl Butanoate and Methyl Pentanoate as Model Compounds for Biodiesel

October 7, 2008

Author(s)

Carrigan J. Hayes, Donald R. Burgess Jr.

Methyl esters are commonly used as surrogates for complex biofuel chemistry; this utility necessitates development of combustion mechanisms for these species. A pathway accounting for early CO2 production in the combustion of methyl esters, using methyl

Findings and Recommendations from the Joint NIST/AFRL Workshop on Rocket Propellants and Hypersonic Vehicle Fuels

September 25, 2008

Author(s)

Thomas J. Bruno, Matt Billingsley, Ron Bates

The Joint NIST/AFRL Workshop on Rocket Propellants and Hypersonic Vehicle Fuels was held on September 25 and 26, 2008 at the Boulder, Colorado laboratories of NIST. The workshop included oral presentations from staff* of NIST, AFRL, CPIAC, NASA, Stanford

Density and Speed of Sound Measurements on Five Fatty Acid Methyl Esters at 83 kPa and Temperatures from (278.15 to 338.15) K

September 20, 2008

Author(s)

Lisa S. Ott, Marcia L. Huber, Thomas J. Bruno

The densities and velocities of sound of five fatty acid methyl esters (FAMEs) were measured at approximately 83 kPa (atmospheric pressure in Boulder, CO) at temperatures from (278.15 to 338.15) K. The FAMEs measured were the five primary components of

Composition-Explicit Distillation Curves of Diesel Fuel with Glycol Ether and Glycol Ester Oxygenates: Fuel Analysis Metrology to Enable Decreased Particulate Emissions

September 17, 2008

Author(s)

Beverly L. Smith, Lisa S. Ott, Thomas J. Bruno

We have recently introduced several important improvements in the measurement of distillation curves for complex fluids. The modifications to the classical measurement provide for (1) a composition explicit data channel for each distillate fraction (for

Isomerization and Decomposition Reactions in the Pyrolysis of Branched Hydrocarbons: 4-Methyl-1-Pentyl Radical

July 31, 2008

Author(s)

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

The kinetics of the decomposition of 4-methyl-1-pentyl radicals have been studied from 927 1068 K at pressures of 1.78 2.44 bar using a single pulse shock tube with product analysis. The reactant radicals were formed from the thermal C I bond fission of 1

July 2, 2008

Author(s)

Jason A. Widegren, Thomas J. Bruno

As part of a larger-scale thermophysical and transport property measurement project, the global decomposition kinetics of the aviation turbine fuel Jet-A was investigated. Decomposition reactions were performed at 375, 400, 425, and 450 °C in stainless
