Phys. Rev. Lett. 75, 2690–2693 (1995)Viscous Effects on Inertial Range Scalings in a Dynamical Model of TurbulenceReceived 16 November 1994; published in the issue dated 2 October 1995 A class of Gledzer-Ohkitani-Yamada shell models for fully developed turbulence is studied numerically in the presence of a hyperviscous damping νkn2+α. It is found that the inertial-range scalings ζp ( 〈|un|p〉∼kn-ζp) are not universal, but depend on the hyperviscosity index α. A class of anomalous scalings are observed, and remarkably ζp/ζ3 are universal. A theoretical explanation is developed based on a recently proposed scaling model of turbulence [She and Leveque, Phys. Rev. Lett. 72, 336 (1994)]. © 1995 The American Physical Society URL:
