This article presents the development of a numerical algorithm for the computation of flow and combustion in a turbine combustor. The flow and combustion are modeled by the Reynolds‐averaged Navier‐Stokes equations coupled with the species‐conservation equations. The chemistry model used herein is a two‐step, global, finite‐rate combustion model for methane and combustion gases. The governing equations are written in the strong conservation form and solved using a fully implicit, finite‐difference approximation. The gas dynamics and chemistry equations are fully decoupled. A correction technique has been developed to enforce the conservation of mass fractions. The numerical algorithm developed herein has been used to investigate the flow and combustion in a one‐stage turbine combustor.
