The Interaction of High-Speed Turbulence with Flames: Global Properties and Internal Flame Structure [PDF]
Combustion and Flame, 157, 5 (2010), pp. 995-1011, 2011 We study the dynamics and properties of a turbulent flame, formed in the presence of subsonic, high-speed, homogeneous, isotropic Kolmogorov-type turbulence in an unconfined system. Direct numerical simulations are performed with Athena-RFX, a massively parallel, fully compressible, high-order, dimensionally unsplit, reactive-flow code.

Influence of DC Electric Field on the Propane-Air Diffusion Flames and NOx Formation
Energies, 2021 The aim of this research is to investigate the effects of a direct current (DC) electric field on the combustion behavior of a co-flow propane diffusion flame. The flame length and NOx emission were observed and measured.

Large Eddy Simulation of a Premixed Bunsen flame using a modified Thickened-Flame model at two Reynolds number [PDF]
Combustion Science and Technology, 2009, 2021 A modified Thickened Flame (TF) model based on Large Eddy Simulation methodology is used to investigate premixed combustion and the model predictions are evaluated by comparing with the piloted premixed stoichiometric methane-air flame data (Chen et al., 1996) for Reynolds numbers Re = 24,000 (flame F3) and Re=52,000 (flame F1).

An experimental study of the detailed flame transport in a SI engine using simultaneous dual-plane OH-LIF and stereoscopic PIV [PDF]
Combustion and Flame 202 16-32 2019, 2020 Understanding the detailed flame transport in IC engines is important to predict ignition, rate of heat release and assess engine performance. This is particularly important for RANS and LES engine simulations, which often struggle to accurately predict flame propagation and heat release without first adjusting model parameters.
