DNS of inhomogeneous reactants premixed combustion
… on the interactions of an initially planar flame with field of inhomogeneous reactants. Unsteady and unstrained laminar methane-air flames are studied in one- and two-dimensional simulations to investigate the effects of normally and tangentially (to the flame surface) stratified reactants. …

Measurements of the structure of turbulent premixed and stratified methane/air flames
… test cases for existing and emerging turbulent flame models, covering a range of u'/sL from 1 to 10, turbulence intensities from 5% to 60%, and stratification ratios from 1 to 3. Simultaneous Rayleigh/Raman/CO-LIF measurements of temperature and major species concentrations - CH4, CO2, CO, H2, …

Fundamental studies of flame propagation in lean-burn natural gas engines
… characteristic time required for steady premixed flame propagation has three components: time for autoignition to occur, time for peak temperature to be achieved following autoignition, and time for steady flame propagation in the premixed fuel/air mixture to be achieved. The autoignition time …

Studies of premixed turbulent flames under flamelet assumptions
… a crucial factor in describing how fast premixed flame can burn, while it is still not well-predictable under various turbulence levels and flame conditions. A clearer definition of turbulent burning velocity based on the reaction rate will help understand the mechanism of turbulent premixed …
