Eulerian spatio-temporal correlations in passive scalar turbulence
Anastasiia Gorbunova, Carlo Pagani, Guilaume Balarac +2
We study the spatio-temporal two-point correlation function of passively advected scalar fields in the inertial-convective range in three dimensions by means of numerical simulatio…

Spatio-temporal correlation functions in scalar turbulence from functional renormalization group
Carlo Pagani, Léonie Canet
We provide the leading behavior at large wavenumbers of the two-point correlation function of a scalar field passively advected by a turbulent flow. We first consider the Kraichnan…
