Assessment of the Composition and Distillation Properties of Thermally Stressed RP-1 and RP-2: Application to Fuel Regenerative Cooling

September 28, 2011

Author(s)

Bret Windom, Thomas J. Bruno

In this work, we measured the volatility of thermally stressed samples of RP-1 and RP-2 rocket kerosenes by use of the advanced distillation curve method. This work is part of a large program at NIST and other laboratories geared toward improving the

Characterization of Renewable Fuels and Additives with the Advanced Distillation Curve Method

August 28, 2011

Author(s)

Thomas J. Bruno, Tara M. Lovestead, Bret Windom

The analysis of complex fluids such as fuels poses significant challenges arising primarily from the multiplicity of components, the different properties of the components (polarity, polarizability, etc) and matrix properties (such as dirty samples)

O2 A-band line parameters to support atmospheric remote sensing. Part II: The rare isotopologues

July 21, 2011

Author(s)

Joseph T. Hodges, David A. Long, Daniel K. Havey, S. S. Yu, M Okumura, Charles E. Miller

Frequency-stabilized cavity ring-down spectroscopy (FS-CRDS) was employed to measure over 100 transitions in the R-branch of the b1Σg+←X3Σg-(0,0) band for the rare O2 isotopologues. The use of 17O- and 18O-enriched mixtures allowed for line positions to be

Density and Speed of Sound Measurements of Two Synthetic Aviation Turbine

June 29, 2011

Author(s)

Stephanie L. Outcalt, Tara J. Fortin

Rising prices and the uncertain supply of petroleum based aviation fuels have led to an interest in substitute fuels made from non-petroleum sources. Synthetic isoparaffinic kerosenes (S-IPK) are among the most promising alternatives. Two instruments were

Hydrogen storage measurements in novel Mg-based nanostructures produced via rapid solidification and devitrification

June 22, 2011

Author(s)

Eric Lass

Nanostructured materials for hydrogen storage with a composition of Mg85Ni15-xMx (M=Y or La, x=0 or 5) are formed by devitrification of amorphous and amorphous-nanocrystalline precursors produced by melt-spinning. All three compositions exhibit a maximum

PDH-locked, frequency-stabilized cavity ring-down spectrometer

June 16, 2011

Author(s)

Joseph T. Hodges, A. Cygan, Piotr Maslowski, Katarzyna E. Bielska, S. Wojtewicz, J. Domyslawska, Hisashi Abe, R.S. Trawinski, R. Ciurylo

We describe a high sensitivity and high spectral resolution laser absorption spectrometer based upon the frequency-stabilized cavity ring-down spectroscopy (FS-CRDS) technique. We used the Pound-Drever-Hall (PDH) method to lock the probe laser to the high

QUANTIFICATION OF A PRECISION POINT SOURCE FOR GENERATING CARBON DIOXIDE EMISSIONS

June 10, 2011

Author(s)

Robert P. Borthwick, Matthew Bundy

This study provides an analysis of the uncertainty of carbon dioxide (CO2) emissions from an 8 MW natural gas burner. A precise and accurate point source for industrial quantities of carbon dioxide can be used to evaluate the performance of stack gas

Comparison of Diesel Fuel Oxygenate Additives with Composition-Explicit Distillation Curve Method Part 3: t-Butyl Glycerols

May 2, 2011

Author(s)

Tara Lovestead, Thomas J. Bruno

Interest in the domestic production of all fuels, sparked by the high cost of petroleum crude oil, has led to consideration of fluids to replace or extend conventional petroleum-derived fuels. There is particular interest in formulating oxygenated diesel

Comparison of Diesel Fuel Oxygenates with Composition-Explicit Distillation Curve Method Part 1: Linear Compounds with One to Three Oxygens

May 2, 2011

Author(s)

Thomas J. Bruno, Tara Lovestead, Jennifer Riggs, Erica Jorgensen, Marcia L. Huber

There is a great deal of interest in formulating oxygenated diesel fuels that produce low particulate emissions. The most common oxygenating additives for diesel fuels include the glycol ethers, glycol esters, alcohols, ethers and ketones. It is important

Method and Apparatus for the Thermal Stress of Complex Fluids: Application to Fuels

May 2, 2011

Author(s)

Thomas J. Bruno, Bret Windom

In this brief paper we describe a simple apparatus that can produce sufficient quantities of thermally stressed complex fluids (such as fuels) to allow a full range of thermophysical property measurements to be performed on the resulting fluid. The

Measurement and Correlation of the Thermal Conductivity of Biodiesel Constituent Fluids: Methyl Oleate and Methyl Linoleate

April 26, 2011

Author(s)

Richard A. Perkins, Marcia L. Huber

New experimental data on the thermal conductivity of the methyl esters methyl oleate and methyl linoleate in the liquid phase are reported that allow the development of correlations. These new experimental data, covering a temperature range of 302 K to 509
