Large-eddy simulation of the turbulent diffusion flame

Large-eddy simulation of a turbulent piloted methaneÕair diffusion flame „Sandia flame D..

The Lagrangian Flamelet Model is formulated as a combustion model for large-eddy simulations of turbulent jet diffusion flames. The model is applied in a large-eddy simulation of a piloted partially premixed methane/air diffusion flame ~Sandia flame D!. The results of the simulation are compared to experimental data of the mean and RMS of the axial velocity and the mixture fraction and the unco...

Large eddy simulation of a turbulent diffusion flame with Conditional Source-term Estimation

1. Motivation and objectives Direct numerical simulation (DNS) of turbulent reacting flows at technically relevant high Reynolds numbers will be computationally unaffordable for the foreseeable future. Large eddy simulation (LES) represents an attractive alternative. The basic idea of LES is to resolve only the large scale motion of the flow while modeling the contribution of the small (i.e. su...

Error analysis of large-eddy simulation of the turbulent non-premixed sydney bluff-body flame

A computational error analysis is applied to the large-eddy simulation of the turbulent non-premixed Sydney bluff-body flame, where the error is defined with respect to experimental data. The errorlandscape approach is extended to heterogeneous compressible turbulence, which is coupled to combustion as described by a flamelet model. The Smagorinsky model formulation is used to model the unknown...
