| Outline of Final Research Achievements |
Turbulent flows are unpredictable flows with complex behavior. One way to understand such complex flows is to consider mean flow. However, there is the infamous closure problem of turbulence, in which the system of time evolution equations for mean flow is not closed.
Here, in order to close the mean flow system of equations, the closure equations for mean flow are derived assuming that the Lagrangian velocity is normally distributed. In the case of infinite Reynolds number, the Kolmogorov energy spectrum is reproduced including the Kolmogorov constant.
