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

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
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

The NIST ThermoData Engine (TDE) is a large electronic database containing experimental data with detailed descriptions of relevant metadata and uncertainties that incorporates expert- system software to automatically generate dynamically evaluated data

A fundamental experimental and numerical study of the water transport across a perfluorosulfonic acid (PFSA) membrane under a temperature gradient is presented. The water transport phenomenon was experimentally investigated through water flux measurement
The distillation curve is the only practical measurement used to characterize the vapor/liquid equilibrium (volatility) of a complex mixture. In earlier work, we described an improved method and apparatus for distillation curve measurement at atmospheric
The purpose of this work was to determine vapor pressures for saturated biodiesel esters at the low-temperature end of their liquid range. A "concatenated" gas saturation apparatus capable of simultaneous measurements on 18 samples was used for

The natural and forced mixing and dispersion of hydrogen released in an accidental manner in a partially enclosed compartment with vents at multiple heights is investigated using theoretical tools. The key to the analysis is determination of the position

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
