Critical Exponents and Universality in Fully Developed Turbulence
Bhimsen K. Shivamoggi
Abstract
Multi-fractal model for dissipation field has been used to provide a detailed structure for the critical exponent σdescribing the scaling form of dissipation εthat appears to exhibit an interesting universality covering radically different hydrodynamic fully developed turbulence (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.
