Abstract
Using direct numerical simulations we study the spatiotemporal correlations of passive scalars advected both by Navier-Stokes flow and by synthetic velocity fields. Beyond their global behavior, which is either a Gaussian or an exponential decay in time, depending on the carrier flow, we determine with accuracy the prefactors in the exponents, and find a remarkable agreement with recent results from functional renormalization group.
