For small inertial subrange, KS is efficient and the significance of the sweepingcan be ignored, as a result we limit the KS agreement with the Richardson scaling law t3 forinertial subrange kN/k1 ≤ 10000. Above this value, the sweeping effect of the small scales bythe large scales must be taken in considerations where KS failed to reproduces this power lawin that range as obtained in [13].
