摘要：

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 512(2) 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.
