Outline of Final Research Achievements |
An improved subgrid-scale (SGS) model was proposed by combining an isotropic linear eddy-viscosity term with an extra anisotropic term. This model has no serious negative effects on the computational stability under coarse grid conditions. Furthermore, using this SGS model, the present LES/RANS model can successfully cover a much wider range of flow domain by LES compared with the model previously proposed by our group.
