On scaling and statistical geometry in passive scalar turbulence
arXiv:0903.2731 · doi:10.1103/PhysRevLett.99.144502
Abstract
We show that the statistics of a turbulent passive scalar at scales larger than the pumping may exhibit multiscaling due to a weaker mechanism than the presence of statistical conservation laws. We develop a general formalism to give explicit predictions for the large scale scaling exponents in the case of the Kraichnan model and discuss their geometric origin at small and large scale.
