Critical Exponents and Universality in Fully Developed Turbulence

Bhimsen Shivamoggi
University of Central Florida

Multi-fractal model for hydrodynamic fully developed turbulence (FDT) has been used to provide a detailed structure for the critical exponent describing the scaling form of energy (or enstrophy) dissipation rate that appears to exhibit an interesting universality covering radically different hydrodynamic FDT systems.  This result also appears to provide a consistent framework for classification of dissipation field into critical, subcritical and supercritical cases.  Some FDT problems that exemplify these cases are discussed.
