## Asymptotic behaviour of the Direct Interaction Approximation.

Asymptotic behaviour of the Direct Interaction Approximation. As mentioned previously, Kraichnan’s asymptotic solution of the DIA, for high Reynolds numbers and large wavenumbers, did not agree with the observed asymptotic behaviour of turbulence. His expression for the spectrum was , where is the root-mean-square velocity and is a constant. In 1964 (see [1] for theContinue reading Asymptotic behaviour of the Direct Interaction Approximation.
