DIFFUSION-COEFFICIENTS AND EFFECTIVE VISCOSITY OF SUSPENSIONS OF STICKY HARD-SPHERES WITH HYDRODYNAMIC INTERACTIONS

We study the short-time and long-time diffusion coefficients and the high-frequency and zero-frequency effective viscosity of a dilute suspension of sticky hard spheres with hydrodynamic interactions. Due to the singular nature of the hydrodynamic interactions near touching the transport coefficients are strongly affected by the short-range attractive potential. This suggests that the transport coefficients may be used as a test of the interaction potential. © 1990 American Institute of Physics.
