Theoretical Analysis for Shear Prediction in Stirred Cell

2 Theoretical Analysis for Shear Prediction in Stirred Cell Turbulent Shear Relationships 

Before the relevant turbulent shear can be assessed, it is necessary to know the scale of interest and understand its relevance to the turbulent cascade (transfer of energy from large to small scales). The Kolmogoroff microscale Lt is given by  

For scales of motion L less than and larger than Lk the turbulent velocity scale u is given bye 

Particle agglomerates of diameter dp where dp Lk (the most likely case) will be subject to shear associated with the turbulent length scale L = dp. Thus the shear influencing the particle agglomerates will be  

In order to estimate the shear, it is necessary to determine the turbulent dissipation.
