Title | new skeletal mechanism for n-heptane MILD combustion |
Description | A chemical kinetic mechanism describing the combustion of n-hetane liquid fuel under MILD condition is developed using a well established computer code/methdology called CARM which used steady state and partial equilibrium approximations for species and reactions with fast time scales. The mechanism developed is suitable for high fidelity simulations of turbulent combustion of practical interest. A manuscript describing the methodology, the mechanism and results are published (under review in journal Combustion and Flame) and thus this information will become available to others. |

Impact | An accurate description of chemical kinetics for n-heptable combustion in turbulent flows with large diluent species and this condition is of interest for next generation of combustion systems. |
Title | chemical kinetic skeletal mechanism for n-heptane |
Description | This combustion chemistry model allows us to represent the chemical pathways of n-heptane oxidation in turbulent combustion simulations at a low computational cost with very good accuracy. Also, the fundamental characteristics such as flame speed, ignition delay, high-temperature ignition, which are relevant for MILD (or "green") combustion technology can be computed easily and quickly. |
