An aerosol rapid compression machine for studying energetic-nanoparticle-enhanced combustion of liquid fuels

The use of energetic nanoparticles offers a promising means of adjusting the reactivity of liquid fuels for enhanced combustion stability in next generation propulsion systems. This work outlines the development of a novel aerosol rapid compression machine (RCM) for studying the impact of energetic nanoparticles on reducing the ignition delay of liquid fuels, and a proof-of-concept demonstratio...

Combustion Reactions of Paraffin Components in Liquid Transportation Fuels Using Generic Rates

The approach of mechanism generation is the accepted one of assigning generic rates to reactions in the same class. The procedure has been successfully applied to higher paraffins that include detailed sub-models of n-hexane, cyclohexane, n-heptane, n-decane, n-dodecane, and n-hexadecane and semi-detailed submodels of iso-octane and methyl cyclohexane, in addition to reactions of aromatic forma...

Developing Surrogates for Liquid Transportation Fuels: The Role of Spherically Symmetric Droplet Combustion

The finite supply of transportation fuels has generated renewed interest to improve their performance in power and propulsion devices. However, the complexity of real fuels prohibits developing their combustion chemistries and property databases needed for simulating performance in engines to identify operational regimes for improving fuel efficiency. Surrogates offer the means to address these...

Progress in the Development of a Combustion Kinetics Database for Liquid Fuels

We describe our progress in the development of chemical kinetics databases for liquid fuels. The intention is to create kinetics databases that can be used to simulate all aspects of combustion across a wide range of equivalence ratios. This paper will include some brief comments on existing databases, a summary of current work and a discussion of future directions. Liquid fuels are complex mix...
