Small Skeletal Kinetic Mechanism for Kerosene Combustion

Research output: Contribution to journalArticle


The development and validation of a new skeletal mechanism for kerosene combustion, suitable for reacting direct-, large-eddy, and Reynolds averaged Navier-Stokes Simulations, are presented. The mechanism consists of 65 irreversible reactions between 22 species and is built on a global fuel breakdown approach to produce a subset of C2 intermediates. A more detailed set of reactions for H/O/C1 chemistry largely determines the combustion characteristics. The mechanism is validated for combustion characteristics related to ignition, flame propagation, and flame extinction over a wide range of pressure, temperature, and equivalence ratios. Agreement with experiments and a more complex reference mechanism are excellent for laminar burning velocities and extinction strain rate, while ignition delays are overpredicted at stoichiometric and rich conditions. Concentration profiles for major stable products are in agreement with reference mechanism, and also a range of intermediate species and radicals shows sufficient agreement. The skeletal mechanism shows an overall good performance in combination with a numerical stability and short computation time, making it highly suitable for combustion Large Eddy Simulation (LES).
