The modified cumulant expansion for two-dimensional isotropic turbulence.

T. Tatsumi, S. Yanase

Research output: Contribution to journalArticlepeer-review


The two-dimensional isotropic turbulence in an incompressible fluid is investigated using the modified zero fourth-order cumulant approximation. The dynamical equation for the energy spectrum obtained under this approximation is solved numerically and the similarity laws governing the solution in the energy-containing and enstrophy-dissipation ranges are derived analytically.
