On the anisotropy of the turbulent passive scalar in the presence of a mean scalar gradient
We investigate the origin of the scalar gradient skewness in isotropic turbulence on which a mean scalar gradient is imposed. The problem of the advection of an anisotropic scalar field is reformulated in terms of the advection of an isotropic vector field. For this field triadic closure equations are derived. It is shown how the scaling of the scalar gradient skewness depends on the choice of ...
متن کاملConditional statistics for a passive scalar with a mean gradient and intermittency
The conditional dissipation and diffusion for a passive scalar with an imposed mean gradient are studied here. The results are obtained for an elementary model consisting of a random shear flow with a simple time-periodic transverse sweep. As the Peclet number is increased, scalar intermittency is observed; the scalar probability density function departs strongly from a Gaussian law. As a resul...
متن کاملPassive scalar turbulence in high dimensions.
Exploiting a Lagrangian strategy we present a numerical study for both perturbative and nonperturbative regions of the Kraichnan advection model. The major result is the numerical assessment of the first-order 1/d expansion by Chertkov, Falkovich, Kolokolov, and Lebedev [Phys. Rev. E 52, 4924 (1995)] for the fourth-order scalar structure function in the limit of high dimension d's. In addition ...
متن کاملMean-field theory for a passive scalar advected by a turbulent velocity field with a random renewal time.
Mean-field theory for turbulent transport of a passive scalar (e.g., particles and gases) is discussed. Equations for the mean number density of particles advected by a random velocity field, with a finite correlation time, are derived. Mean-field equations for a passive scalar comprise spatial derivatives of high orders due to the nonlocal nature of passive scalar transport in a random velocit...
متن کاملMean Field for Continuous High-Order MRFs
Probabilistic inference beyond MAP estimation is of interest in computer vision, both for learning appropriate models and in applications. Yet, common approximate inference techniques, such as belief propagation, have largely been limited to discrete-valued Markov random fields (MRFs) and models with small cliques. Oftentimes, neither is desirable from an application standpoint. This paper stud...
