Numerical simulation of premixed turbulent methane combustion [PDF]
Proceedings of the Combustion Institute, 2002 With adaptive-grid computational methodologies and judicious use of compressible and low Mach number combustion models, we are carrying out three-dimensional, time-dependent direct numerical simulations of a laboratory-scale turbulent premixed methane burner.

Simulation of lean premixed turbulent combustion
Journal of Physics: Conference Series, 2006 There is considerable technological interest in developingnew fuel-flexible combustion systems that can burn fuels such ashydrogenor syngas. Lean premixed systems have the potential to burn thesetypes of fuels with high efficiency and low NOx emissions due to reducedburnt gas temperatures.
