Fully developed isotropic turbulence: Nonperturbative renormalization group formalism and fixed-point solution
We investigate the regime of fully developed homogeneous and isotropic turbulence of the Navier-Stokes (NS) equation in the presence of a stochastic forcing, using the nonperturbative (functional) renormalization group (NPRG). Within a simple approximation based on symmetries, we obtain the fixed point solution of the NPRG flow equations that corresponds …
