Abstract

The present research deals with the development of a new combustion model in numerical simulations of turbulent premixed combustion. This research is performed in the framework of the application of biogas additions to natural gas as combustibles in domestic and industrial applications. We start from the point of view of detailed calculations. To that end for the aerodynamics we take a DNS code and for the combustion detailed kinetics is taken into account for laminar flames. In order to access practical problems these methods have to be reduced. For this we introduced the Flamelet Generated-Manifolds method in the DNS to obtain accurate chemistry effects at low computational cost. The next steps are the reduction of the aerodynamics by LES and RANS respectively. Then also effects of flame stretch and curvature have to be taken into account.
