From Navier-Stokes turbulence numerical simulations we show that for the extended self-similarity ~ESS! method it is essential to take the third order structure function taken with the modulus and calledD3* (r ), rather than the standard third order structure function D3(r ) itself. If this is done, we find ESS towards scales larger than order;10h, whereh is the Kolmogorov scale. If D3(r ) is used, there is no ESS. We also analyze ESS within the Batchelor parametrization of the second and third… CONTINUE READING
