Chaotic Lagrangian models for turbulent relative dispersion.
A deterministic multiscale dynamical system is introduced and discussed as a prototype model for relative dispersion in stationary, homogeneous, and isotropic turbulence. Unlike stochastic diffusion models, here trajectory transport and mixing properties are entirely controlled by Lagrangian chaos. The anomalous "sweeping effect," a known drawback common to kinematic simulations, is removed thr...
متن کاملOdour dispersion modelling with Lagrangian and Gaussian models
The Lagrange particle diffusion model LASAT and the Gaussian Austrian Odour Dispersion Model AODM are used to calculate direction-dependent separation distances around livestock farms. As the method has been published already in several papers, the focus is here on the differences of the results due to model physics. With both models, the same peak-to-mean algorithm is used to calculate short-t...
متن کاملHistory of Lagrangian Stochastic Models for Turbulent Dispersion
Lagrangian Mode Geophysical Mon © 2012. American 10.1029/2012GM This article briefly summarizes the historical evolution of the modern Lagrangian stochastic (LS) class of models for the calculation of fluid element (or particle) paths in turbulence. The fundamental advantages of a “first-order” LS model relative to alternative descriptions of turbulent dispersion are (1) its ability to correctl...
متن کاملDevelopment of an Odor Concentration Model and Software for Modeling Peak Odor Concentration
Odors, once tolerated as a sign of industrial prosperity are now perceived as an evidence of environmental problems. Increasing complaints from citizens regarding the noxious odors has coerced industries into addressing this "odor issue". Properties of odor are unique, due to the nature of requirements for their measurement. This can be attributed to the subjective responses of humans to variou...
متن کاملInfluence of Eulerian and Lagrangian scales on the relative dispersion properties in Lagrangian stochastic models of turbulence.
The influence of Eulerian and Lagrangian scales on the turbulent relative dispersion is investigated through a three-dimensional Eulerian consistent Lagrangian stochastic model. As a general property of this class of models, it is found to depend solely on a parameter beta based on the Kolmogorov constants C(K) and C0. This parameter represents the ratio between the Lagrangian and Eulerian scal...
