Abstract

We apply the error-landscape analysis to turbulent non-premixed combustion in a bluff-body flame and investigate the error-reduction that can be achieved by adopting the SIPI algorithm (succesive inverse polynomial interpolation) for direct optimization of the combined effect of discretization and modeling errors. Small scale turbulent flow aspects are modeled using the Smagorinsky model and a flamelet formulation is adopted for the combustion process. A systematic study of numerical predictions at various resolutions and different levels of subgrid dissipation is conducted, providing an overview of partial error-cancellation. The general structure of the error-landscape is similar to that found for single phase homogeneous isotropic flow - the application of SIPI results in a considerable reduction of the total error (15-50 % improvement in relative error) after a small number of iterations. The SIPI approach provides an impression of the sensitivity of predictions on numerical and modeling parameters
