Abstract

In this article, we study the turbulent diffusion of the dispersion-dissipation equations, especially the KdV-Burgers equation. Using the concept of renormalization, we prove that the renormalized equation is the diffusion equation for short-range correlation, while for long-range correlation, it is the superdiffusion equation.
