Notes:
The application of Kraichnan's Direct Interaction Approximation [J. Fluid Mech. 5, 497 (1959)] to the inertial range of Navier–Stokes turbulence is examined. A similarity form valid in the inertial range is presented, along with several approximations permitting explicit solutions. The relationship of the present results to some recent renormalization-group calculations is discussed. It is shown that these renormalization-group calculations misrepresent the Direct Interaction Approximation's nonlinear interaction and that the addition of an artificial stirring force is unnecessary.
