Large-Eddy Simulation of Autoignition-Dominated Supersonic Combustion [PDF]
, 2015 The simulation of low-speed combustion flows is well established. However, at high-speed conditions where radical formation and ignition delay are important, there is much less experience with turbulent combustion modeling.

Detailed simulations for flamelet modelling of SOx formation from coal
Proceedings in Applied Mathematics and Mechanics, Volume 19, Issue 1, November 2019., 2019 Abstract This paper reports on recent progress in the modelling of pulverised coal flames. A brief review of current research on fully‐resolved and Euler‐Lagrange simulations in the context of flamelet modelling of pulverised coal combustion is given first. This is followed by more recent results from the flamelet modelling of SOx formation due to fuel‐
