Where D (u) is the diffusion coefficient of a particle at a distance u.R from another particle, D0 is that of a particle in an infinitely dilute solution, β(u) is the coefficient of hydrodynamic retardation, reflecting the influence of the hydrodynamic interaction of the approaching particles on their diffusivity, given by Honig et al. [10]:
The theoretical computations by Honig et al.[10] predict that hydrodynamic interaction changes the rate of fast coagulation by a factor of about 0.4 to 0.6 in general. |
