One of the most important properties measured for liquid fuels is the volatility, usually as expressed by the distillation curve. In previous work, we introduced the composition explicit or advanced distillation curve (ADC) metrology, which we have applied

Complementary shock-tube studies at the National Institute of Standards and Technology (NIST) and the University of Illinois at Chicago (UIC) have been used to examine the decomposition reactions of the 1-pentyl radical at temperatures of 833 K to 1130 K
Additive packages are used with aviation kerosenes to achieve performance enhancements such as higher or lower operating temperatures or increased lubricity. An additive used to increase operating temperatures for heat sink applications is the +100

The complex nature of finished fuels makes definitive studies on composition and combustion properties very difficult and uncertain. This has led to the adoption of fuel surrogate mixtures in such studies. The development of a surrogate mixture is itself a
The isomerization and decomposition reactions of 2-pentyl and 3-pentyl radicals have been studied in a single-pulse shock tube over a temperature range of 973 K to 1121 K and pressures of 120 kPa to 800 kPa. The results represent the first direct study of
Density, speed of sound, and viscosity has been measured for eleven orthogonal blends of the rocket propellant RP-1. Density and speed of sound were measured over the temperature range of 278 K to 343 K, while viscosity was measured from 263 K to 373 K
In this paper, we report the application of the advanced distillation-curve approach to the gas turbine fuels Jet-A, JP-8, and JP-5, in order to obtain information about the variability of these gas turbine fuels. The measurements of the temperatures Tk

In this work a novel approach is developed to formulate surrogate fuels having characteristics that are representative of diesel fuels produced from real-world refinery streams. Because diesel fuels consist of hundreds of compounds, it is difficult to
Thermochemical conversion of fossil fuels currently dominates the national and global energy portfolio, with the most notable being the stationary power production and transportation vehicles sectors. As global energy demand continues to increase

In recent years, civilian and military users of aviation kerosene have been interested in expanding the scope of fuel feed stocks to include non-petroleum sources. The most well known examples of such alternative sources of fuel are the Fisher-Tropsch

The decomposition and intramolecular H-transfer isomerization reactions of the 1 pentyl radical have been studied at temperatures of 900 K to 1050 K and pressures of 0.8 bar to 6 bar using the single pulse shock tube technique and additionally investigated

The increasing cost of diesel fuel, potential for supply disruptions, and environmental concerns have resulted in a great deal of research to improve the performance and efficiency of diesel engines. This includes significant efforts in the reformulation

There is a great deal of interest in formulating oxygenated diesel fuels that produce low particulate emissions. In this paper, the fourth in a series of papers on the properties of mixtures of diesel fuel with oxygenating additives, we present the
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
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

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
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
Biodiesel fuel is an alternative fuel that can be derived from a number of renewable feedstocks including plant and vegetable oils, algae, animal fats, waste oils, etc. The fatty acid methyl ester (FAME) profile, and thus the resultant properties, of the
In recent years, civilian and military users of aviation kerosene have been interested in expanding the scope of fuel feed stocks to include non-petroleum sources. The most well known examples of such alternative sources of fuel are the Fisher-Tropsch
The p-ρ-T behaviors of four lean synthetic natural gas mixtures were measured along isotherms of 250 K, 350 K, and 450 K with pressures to 37 MPa with a two-sinker, magnetic-suspension densimeter. The gravimetrically prepared mixtures have seven to nine
Densities of the missile fuel JP-10 were measured with two vibrating-tube densimeters. The combined range of the data is from 270 K to 470 K with pressures to 30 MPa. The speed of sound in the fuel was measured with a propagation time method at ambient
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

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
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
