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

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

May 27, 2010

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

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 %

Kinetics of the Thermal Reaction of H Atoms with Propyne

April 15, 2010
Author(s)
Claudette M. Rosado-Reyes, Jeffrey A. Manion, Wing Tsang
The reaction of hydrogen atoms with propyne(CH≡CCH3) has been investigated in a heated single pulse shock tube at temperatures of 870-1145K and pressures of 2-9 bar. Stable products from various reaction channels (terminal and non-terminal H addition, and

Density and Speed of Sound Measurements of Hexadecane

January 7, 2010
Author(s)
Stephanie L. Outcalt, Arno R. Laesecke, Tara J. Fortin
The density and speed of sound of hexadecane have been measured using two instruments. Both instruments use the vibrating-tube method for measuring density. Ambient pressure (83 kPa) density and speed of sound measurements were carried out with a rapid

Effect of RP-1 Compositional Variability on Thermophysical Properties

October 6, 2009
Author(s)
Marcia L. Huber, Eric W. Lemmon, Thomas J. Bruno
We compare experimental and predicted thermophysical properties of two samples of rocket propellant RP-1 obtained from different batches of RP-1 that exhibit compositional variations. One sample is atypical, due to a high olefin content. The effect of the

Thermophysical Properties Measurements of Rocket Propellants RP-1 and RP-2

September 1, 2009
Author(s)
Stephanie L. Outcalt, Arno R. Laesecke, Karin Brumback
The density, speed of sound, and viscosity of two rocket propellants (RP-1 and RP-2) have been measured. The combined range of the data is from 270 K to 470 K with pressures to 40 MPa. The estimated uncertainty of the density data is 0.1 % and that of the

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
