Comparison of the Eulerian and Lagrangian Approaches to Modeling Turbulent Micromixing

RÉSUMÉ
Modeling of turbulent micromixing of a passive isotropic scalar field is carried out on the basis of three Lagrangian models: the method of mapping closure, method of linear root-mean-square approximation, and the method of coalescence — fractionation of particles. Calculation results for the evolution of the dispersion of scalar and of the rate of scalar dissipation are compared for these three stochastic models and also for the model of one of the authors which is based on the equation for the joint probability density function of the scalar and its gradient. All these statistical characteristics are compared with similar data of direct numerical simulation which has been carried out for the same conditions.
