Abstract
The aim of this paper is to evaluate the performance of thermo-chemistry tabulation approaches for numerical simulation of laminar partially premixed flame by comparing with the results of detail chemistry. Two thermo-chemistry tabulation approaches are considered: the multidimensional flamelet manifolds (MFM) method and Flame Prolongation of Intrinsic low-dimensional manifold (FPI) method. The fuel streams with different equivalence ratios (ΦF=1.8,ΦF=2.464) are analyzed. In both of the equivalence ratios the results obtained from MFM method are in closer agreement with the direct calculation than FPI method. It is concluded that multi-dimensional flamelet manifolds can capture more precisely partially premixed characteristic of the multi-regime flame structure, comparing to single-dimensional flamelet model FPI.
