Reynolds-Stress model taking into account strong anisotropy of wall turbulence (1st report, new proposal for reynolds-stress model)

摘要

Taking into account the fact that the state of turbulence approaches a two-dimensional state close to the wall, a new Reynolds-stress turbulence model is proposed. The rotational properties of the two-dimensional turbulence differ significantly from the three-dimensional one. Under the system rotating about the axis perpendicular to the plane the turbulence correlations between fluctuating velocities remain invariant, while those combined with fluctuating pressure vary.
