On lumped-reduced reaction model for combustion of liquid fuels

Reduced Kinetic Models for the Combustion of Jet Propulsion Fuels

Reduced chemical kinetic models to predict the combustion characteristics of jet propulsion fuels are produced and tested. The parent detailed kinetic model has been developed on the basis of a surrogate fuel formulation methodology that utilizes combustion property targets measured for a particular real fuel to formulate a chemical mixture of nalkanes, iso-alkanes and aromatic functionalities ...

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...

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...
