A close analogy between the energy transfer from large to small scales in isotropic turbulence and the momentum transfer in the wall normal direction in WBT plays a key role in the application. The application gives estimates of the influence of the finite Reynolds number on the statistics. The estimates are consistent with data by high-resolution direct numerical simulations of turbulent channel flow.journal articleAmerican Physical Society2019-05application/pdfPhysical Review Letters191221945020031-9007https://nagoya.repo.nii.ac.jp/record/28494/files/PhysRevLett_122_194502.pdfenghttps://doi.org/10.1103/PhysRevLett.122.194502© 2019 American Physical Society
