Two recent intermittency models by Chen and Cao [Phys. Rev. E52, R5757 (1995)] and Nelkin [Phys. Rev. E52, R4610 (1995)] stemming from Novikov’s criticism [Phys. Rev. E50, R3303 (1994)] on the She–Le´ve⁁que model [Phys. Rev. Lett.72, 336 (1994)] are discussed. Both models are rewritten using&mgr;6(deviation from Kolmogorov 1941 of the sixth order structure function exponent) values computed numerically(=0.23and0.43using longitudinal and lateral velocity differences). Scaling exponents are compared. ©1997 American Institute of Physics.
