Abstract

Two‐parametric eddy viscosity (TPEV) and other spectral characteristics of two‐dimensional (2‐D) turbulence in the energy transfer subrange are calculated from direct numerical simulation (DNS) with 512² resolution. The DNS‐based TPEV is compared with those calculated from the test field model (TFM) and from the renormalization group (RG) theory. Very good agreement between all three results is observed.
