We report some results of a series of high resolution direct numerical simulations (DNSs) of forced incompressible isotropic turbulence with up to 122883 grid points and Taylor microscale Reynolds number Rlambda 2300. The DNSs show that there exists a scale range, approximately at 100< r/eta < 600 (eta is the Kolmogorov length scale), where the second-order longitudinal velocit
