The motion of a spherical colloidal particle suspended in a moving fluid near a planar hard wall or free surface is considered. The particle types include hard spheres with mixed slip-stick boundary conditions, droplets with high surface tension and porous particles. A general expression for the...

We study the frequency-dependent viscosity of a suspension of spherical particles on the basis of linear response theory applied to the generalized Smoluchowski equation. Hydrodynamic interactions are fully taken into account. We derive expressions for the frequency-dependent viscosity based on...

We study the orientational time correlation functions of a tracer colloid particle which carries a magnetic moment in the presence of a weak external magnetic field. The tracer interacts with other particles in a low density suspension through hard sphere pair potentials and hydrodynamic forces....

By assuming free rotation and the inverting previously obtained friction tensors, we obtain the mobility tensors describing the hydrodynamic interaction between two permeable spheres through order 1/l7, where l is the particle separation. We show that the dimensionless constants which appear in...

By a method of reflections described in a previous article we construct the approximate velocity field produced by the motion of two permeable spheres through an incompressible fluid. The permeability is described by the Debye-Bueche equations. We consider contributions to the velocity field...

We study small-amplitude swimming of a deformable sphere in a viscous incompressible fluid. We assue that the surface displacement varies harmonically in time and calculate the resulting swimming velocity in perturbation theory to second order in the diplacement. The optimum efficiency of...

We consider a dilute polydisperse suspension of spherical colloidal particles and obtain an expression for the high frequency (short time) effective viscosity of the suspension. We show that the Huggins coefficient for such a suspension is sensitive to the degree and nature of the...

We derive Faxén theorems for the force, the torque and the symmetric force dipole moment acting on a spherically symmetric polymer suspended in arbitrary flow. The results are immediate generalizations of corresponding theorems for a hard sphere with mixed slip-stick boundary conditions.

We consider the Brownian motion of a polymer of arbitrary shape immersed in an incompressible fluid. The polymer is represented as a permeable object which interacts with the fluid in a way described by the Debye-Bueche-Brinkman equations. We apply the ideas of non-equilibrium thermodynamics to...

We extend the generalized Smoluchowski equation to descrbe the diffusional relaxation of position and orientation in a suspension of interacting spherical colloid particles. Considering a tracer particle which interacts with other particles through spherically symmetric pair potentials and with...
