Large Eddy Simulation of a Turbulent Spray Jet Flame Using Filtered Tabulated Chemistry
Journal of Combustion, Volume 2020, Issue 1, 2020., 2020 This work presents Large Eddy Simulations of the unconfined CORIA Rouen Spray Burner, fed with liquid n‐heptane and air. Turbulent combustion modeling is based on the Filtered TAbulated Chemistry model for LES (F‐TACLES) formalism, designed to capture the propagation speed of turbulent stratified flames.

Application of the Evolution-Variable Manifold Approach to Cavity-Stabilized Ethylene Combustion [PDF]
, 2016 For combustion in high-speed flows, radical-formation time scales and ignition delay times may be similar to, or dominate, relevant flow time scales. Reliable modeling of induction and autoignition processes is critical to the prediction of combustor ...
