Abstract
Results of direct numerical simulations of turbulent premixed combustion of methane-air mixture at model conditions in simple cubic computational domain at moderate Reynolds number Reλ∼50 and Karlovitz number Ka∼5 are presented. These conditions correspond to combustion regime with main oxidation reactions localized in thin area. Extended kinetic mechanism of methane oxidation is used for chemical reactions description. Laminar flame velocity values are obtained and compared with other results of 1D and 3D calculations. Thickness, form and local flame front structures are revealed based on computation results.
