J. Vandebovenkamp et Jkg. Dhont, SPINODAL DECOMPOSITION OF COLLOIDAL SYSTEMS - THE EFFECT OF HYDRODYNAMIC INTERACTIONS, Physica. A, 212(3-4), 1994, pp. 239-250
On the basis of the Smoluchowski equation, the effect of hydrodynamic
interactions on spinodal decomposition kinetics is described. For smal
l wavevectors, the rate of decomposition is decreased as a result of h
ydrodynamic interactions, while at larger wavevectors the rate of deco
mposition is increased, and the critical wavevector is shifted upwards
. For short-ranged attractions these effects are more pronounced than
for long-ranged pair-potentials.
