内容記述 | Numerical simulations of two-dimensional forced turbulence suggest that the enstrophy transfer range energy spectrum E(k) a little steeper than k^-3 is robust in the sense that it may be realized in a wave number range under different run conditions. It is shown that such energy spectra fit well E(k)=C_Kη^{2/3} k^-3[ln(k/k_1)]^{-1/3}, where C_K is a dimensionless constant, η the enstrophy transfer rate per unit mass and k_1 a wave number at the bottom of the range. The simulations give C_K ≈1.9 in fairly good agreement with the existing theoretical estimates. | |||||
