Abstract:
Discrete approximation of a flow field using anisotropic meshes causes "unphysical" anisotropy of the resolved part of the Reynolds stress tensor and of the subgrid scale stress tensor if common anisotropy measures such asūīūj/q2- 1/3δijare used in order to characterize the turbulence structure. By evaluating model spectrum tensors the effect is investigated for isotropic and anisotropic turbulence. The deviation from a physical meaningful anisotropy state depends on various parameters such as t...     »
