We re-investigate our previously studied water transport phenomena under nonisothermal conditions by measuring the through-plane liquid water distribution across PEFC components with the state-of-the-art high-resolution neutron radiography. A corrective

Comparison of JP-8 and JP-8+100 with the Advanced Distillation Curve Approach

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

Chemical and Thermophysical Characterization of 1,3,5-triisopropylcyclohexane

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 Decomposition of 2-Pentyl and 3-Pentyl Radicals

Jeffrey A. Manion, Iftikhar A. Awan
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

Compressed-liquid densities of two highly polar + non-polar binary systems

The binary systems ethanol + 2,2,4-trimethylpentane and 2-butanol + 2,2,4-trimethylpentane were studied as models for blends of gasoline with biofuels. Their densities were measured with a vibrating-tube densimeter at compressed-liquid states of three

Methodology for Formulating Diesel Surrogate Fuels with Accurate Compositional, Ignition-Quality, and Volatility Characteristics

Charles J. Mueller, William J. Cannella, Thomas J. Bruno, Bruce Bunting, Heather Dettman, James A. Franz, Marcia L. Huber, Mani Natarajan, William J. Pitz, Matthew A. Ratcliff, Ken Wright
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

Materials Challenges in Carbon Mitigation Technologies

Laura Espinal, Bryan D. Morreale
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
