Stokesian scaling

For Rein < 2 x 10, Stkinso can be seen to increase, showing that small cyclones are less efficient than one would expect from Stokesian scaling. Our defining equation, (8.1.4), for the Stokes number. 

Computational methods are increasingly valuable supplements to experiments and theories in the quest to understand complex liquids. Simulations and computations can be aimed at either molecular or microstructural length scales. The most widely used molecular-scale simulation methods are molecular dynamics. Brownian dynamics, and Monte Carlo sampling. Computations can also be performed at the continuum level by numerical solutions of field equations or by Stokesian dynamics methods, described briefly below. 

Turbulence may also lead to coagulation as a re.sull of inertial effects. When particles of different sizes (masses) are present in the same accelerating eddy, a relative motion is induced between the particles that may lead to collision. Again the scale of the particle motion is confined to distances < X. The mean. square relative velocity between the particles can be approximated using the force balance for Stokesian particles (Chapter 4) ...
