Properties of a 50/50 Mixture of Jet-A + S-8

March 14, 2007
Author(s)
Thomas J. Bruno, Arno D. Laesecke, Stephanie L. Outcalt, Hans-Dieter Seelig, Beverly L. Smith
This report describes measurement efforts performed on the mixture of aviation fuels: Jet-A + S-8*. The primary mixture is a 50/50 (vol/vol) combination of the two fuels. Measurements include chemical analysis, density, viscosity, speed of sound and vapor

Development of an Experimental Database and Kinetic Models for Surrogate Jet Fuels

March 1, 2007

M Colket, T Edwards, S Williams, N Cernansky, D L. Miller, Fokion N. Egolfopoulos, P Linstedt, Ram Seshadri, F L. Dryer, C K. Law, Daniel G. Friend, David Lenhert, Heinz Pitsch, A Sarofim, M Smooke, Wing Tsang
The engineering and scientific community ha been searching for the identification of surrogate fuels that can reasonably represent the performance and emissions behavior of jet fuels (e.g. Jet A and JP-8) in engines. Many proposals exist in the literature

PEM Fuel Cell Membrane Hydration Measurement by Neutron Imaging

November 8, 2006
Author(s)
D J. Ludlow, M K. Jensen, C M. Calebrese, G A. Eisman, S Yu, C Dannehy, Daniel S. Hussey
Neutron scattering experiments on a proton exchange membrane fuel cell wereperformed to assess the ability to quantify water in the membrane and electrode/gas diffusion layers. Previous studies have shown that liquid water is easily resolved within flow

Method and Apparatus for Precision In-Line Sampling of Distillate

February 26, 2006
Author(s)
Thomas J. Bruno
In this short note we present a method and a simple apparatus for use with simple, fractional and steam distillation operations in which the operator requires a precise measurement of instantaneous distillate composition as the distillation proceeds. There

Method for Estimating the Dielectirc Constant of Natural Gas Mixtures

January 11, 2005
Author(s)
Allan H. Harvey, Eric W. Lemmon
A method is developed for calculating the static dielectric constant (relative permittivity) of fluid mixtures, with an emphasis on natural gas. The dielectric constant is calculated as a function of temperature, density, and composition; the density is

Distinguishing the Relative Contribution of Fossil Fuel and Biomass Combustion Aerosols Deposited at Summit, Greenland through Isotopic and Molecular Characterization of Insoluble Carbon

September 1, 2002
Author(s)
J F. Slater, Lloyd A. Currie, J E. Dibb, Bruce A. Benner Jr
Although the earth's polar regions are isolated from most industrial activity, combustion-generated particles from both fossil fuel and biomass burning impact the regions. Most efforts aimed at quantifying the input of combustion aerosols at Summit
