As already mentioned in the chapter Tracking Global Flows of E-Waste Additives by Using Substance Flow Analysis, With a Case Study in China, China not only generates very high amounts of domestic e-waste due to their fast consumption... 

On the reverse, how does the presence of particles affect local and global flow features in the vessel such as the vortex structure in the vicinity of the impeller, power consumption, circulation and mixing times, and the spatial distribution of turbulence quantities more specifically colliding particles have an impact on the liquid s turbulence (Ten Cate et al., 2004) while local particle concentrations affect the effective (slurry) viscosity which may be useful in the macroflow simulations ...

The models of flow dispersion are based on the plug flow model. However, in comparison with the PF model, the dispersion flow model considers various perturbation modes of the piston distribution in the flow velocity. If the forward and backward perturbations present random components with respect to the global flow direction, then we have the case of an axial dispersion flow (ADF). In addition, the axial and radial dispersion flow is introduced when the axial flow perturbations are coupled with other perturbations that induce the random fluid movement in the normal direction with respect to the global flow. 

If we want to make a more complete stochastic model, it is recommended to consider a process with three elementary states which are the microparticles motion in the direction of the global flow, the microparticles fixation by the collector elements of the porous structure and the washing of the fixed microparticles. In this case, we obtain a model with six parameters aj2, Ui3, U2i> 23> 3i> 32- This is a rather complicated computation.

Mesocopic flows are important to understand because they hold the key to the interaction between the macroscopic flow and the microstructural inhomogeneities. This is especially true in colloidal flows, which involve colloidal mixtures, thermal fluctuations and particle-particle interactions. Dynamic processes occurring in the granulation of colloidal agglomerate in solvents are severely influenced by coupling between the dispersed microstructures and the global flow. On the mesoscale, this... 

For non-reacting fluids the studies of turbulent mixing can be divided into three categories, the gross scale observations of the global flow pattern, fine scale analysis, and experimental studies on the whole turbulent energy spectra.
