- 論文の詳細を見る
The dynamics of the inviscid truncated system of rotating turbulence is studied by numerical simulations under various initial conditions and rotation rates. The simulations suggest that the rotating inviscid truncated system ultimately relaxes towards an equipartition state with energy isotropically distributed at all scales of motion regardless of the initial conditions. Rotation delays relaxation to equipartition in a strongly scale-dependent and anisotropic manner. There is some transient tendency to two-dimensionalize an initially isotropic non-equilibrium state and to maintain initially quasi-twodimensional initial conditions. Both trends are enhanced by increasing the rotation rate.
