Abstract
We investigate the depletion of nonlinearity in isotropic turbulence using aMarkovianized version of the Direct Interaction Approximation (DIA). It is shown that this depletion is present in both the inertial range and dissipation range scales at high Reynolds numbers. The mixing of a passive scalar shows a similar depletion of advection.
