Turbulent mixing

Abstract

Knowledge of turbulent dispersion plays a significant part in various problems of chemical engineering, pharmacology and hydrology investigations related to protection of the environment. Turbulent mixing, in multi-scale systems is studied here. Wavelets based on Hermite polynomials are the solutions obtained by model categorification. The SDG solution for dispersion and the dispersion effects associated to convective flows is presented. The energy intermittency by vortex line stretching characteristic to turbulent flow shows in multi-scale situations new regimes of instability. © 2011 Springer-Verlag Berlin Heidelberg.
