部分予混合バーナー乱流火炎による改良2スカラーフレームレットモデルの適用

抄録

In this research, in order to improve prediction accuracy of numerical analysis of turbulent non-premixed combustion field, numerical analysis is performed by applying an improved combustion model to a turbulent combustion field by a coaxial methane burner, and A comparison was made with experimental result. We calculated with LES as turbulence model and modified 2 scalar framelet approach with level set function considering flame thickness and flame surface curvature as combustion model. As a result, it turned out that the model improves the prediction accuracy of the temperature compared with conventional model in the fuel lean region and the fuel rich region.
