Statistical Model of Turbulent Dispersion Recapitulated

A comprehensive summary and update is given of Brouwers’ statistical model that was developed during the previous decade. The presented recapitulated valid for general inhomogeneous anisotropic velocity statistics are typical turbulence. It succeeds improves semiempirical heuristic models century. based on a Langevin diffusion equation which derivation involves (i) application principles physics stochastic theory; (ii) theory turbulence at large Reynolds numbers, including Lagrangian versions Kolmogorov limits; (iii) systematic expansion in powers inverse universal constant C0, C0 about 6. unique collected chemistry. Presented results include generally applicable expressions turbulent coefficients can be directly implemented numerical codes computational fluid mechanics used environmental industrial engineering praxis. This facilitates more accurate reliable prediction distribution mean concentration passive or almost admixture such as smoke, aerosols, bacteria, viruses flow, all issues great societal interest.
