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)
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

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

The reaction of propene(CH3CH=CH2) with hydrogen atoms has been investigated in a heated single-pulsed shock tube at temperature between 929K-1212K and pressures of 1.7bar-3.4bar. Stable products from H atom addition and H abstraction have been identified

Diminishing petroleum reserves, the potential of supply disruptions, price volatility, as well as environmental considerations resulting from polluting emissions, have led to development of alternative liquid fuels and fuel additives produced from

RP-1 is a long-established hydrocarbon fuel that continues to be widely used as the kerosene component in rocket propulsion systems. The desire in recent years to use rocket motors many times, rather than a single time, has led to reformulations of RP-1

The density of a flightline jet fuel (JP-8) was measured with two vibrating-tube densimeters. The combined range of the data is from 270 K to 470 K with pressures to 40 MPa. The speed of sound in the fuel was measured with a propagation time method at
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

This report contains a summary of research conducted to develop a standard or accepted set of thermophysical properties for the aviation kerosene, JP-8. This report is the culmination of a three year effort that included the participation of most of the

RP-1 is a long-established hydrocarbon fuel that continues to be widely used as the kerosene component in rocket propulsion systems. The desire in recent years to use rocket motors many times, rather than a single time, has led to reformulations of RP-1
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 %

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
Interest in the domestic production of bio-derived fuels, sparked by the high cost of petroleum crude oil, the potential of supply disruptions, and fears about climate change has lead to consideration of fluids to replace or extend conventional petroleum

The density and speed of sound of 1- and 2-butanol 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 from 278
The decomposition kinetics of the kerosene-based rocket propellants RP-1 and RP-2 was studied. For RP-2, decomposition reactions were performed at 375, 400, 425, and 450 °C. For RP-1, decomposition reactions were only performed at 450 °C because we had
The thermal decomposition of RP-2 with three potential stabilizing additives was investigated. The additives were 1,2,3,4-tetrahydroquinoline (THQ), 1,2,3,4-tetrahydronaphthalene (tetralin) and the additive package that is used to make JP-8+100 (herein

We used a quasi-spherical cavity resonator to measure the relative dielectric permittivity ε r of H 2 at frequencies from 2.4 GHz to 7.3 GHz, at pressures up to 6.5 MPa, and at the temperatures 273 K and 293 K. The resonator was calibrated using auxiliary

We have recently introduced several important improvements in the measurement of distillation curves of complex fluids. The modifications to the classical measurement provide for (1) a composition explicit data channel for each distillate fraction (for
JP-7 is a hydrocarbon-based kerosene fraction with a low volatility and high thermal stability. JP-7 was developed in the 1950s to meet the more stringent requirements necessary for the development of high-altitude reconnaissance planes that fly at speeds

Silicon and silicon dioxide form what is arguably the most important technological interface. With the end of Moore s-law scaling for silicon fast approaching, alternatives to silicon dioxide are being pursued that may enable new device architectures and
While the use of ethanol and ethanol blends as motor fuels dates back to the earliest vehicles, ethanol has recently received extraordinary attention as a renewable liquid fuel. In the United States, the application of this fluid is mainly as an additive
