Notes:
From a simple kinetic viewpoint for the formation and rupture of links among primary particles, the pseudoplastic behavior of suspensions can be well described. At steady state, the formation and rupture of links reach a dynamic equilibrium, and the viscosity of suspension is proportional to the state of aggregates. It is assumed that the formation of links is due to the surface forces over particles, including van der Waals' force, and is independent of shear rate. The rupture of links is proportional to ṙm. Finally we get a very simple equation to predict the viscosity of suspension. With this simple kinetic viewpoint, the pseudoplastic behavior of suspensions composed of binary blends of monosize particles is also predictable.
