We solve the creeping flow equations for two spherically symmetric particles immersed in an incompressible fluid. The flow pattern outside the particles is analyzed in a two-center expansion of spherical waves scattered from each of the particles. Hence we construct the friction matrix which...

We formulate the solution of the linear Navier-Stokes equations for steady, incompressible flow about a spherical particle as an expansion of scattered waves. The amplitudes of the outgoing waves are simply related to a set of spherical force multipoles. These multipoles are found from the...

We consider the solution of the creeping flow equations for two spherical particles immersed in an incompressible fluid. For an externally imposed linear flow and for given forces and torques we calculate the translational and rotational velocities of the particles and their symmetric force...

We study the high frequency effective viscosity of suspensions of spherical particles and of emulsions of spherical fluid droplets. Assuming that in the bulk of the dispersion the distribution of particles on average is uniform and isotropic we derive an exact expression for the effective...

Thermal fluctuations in monodisperse colloidal suspensions are investigated on the basis of a linear Langevin approach including nonlocal and memory effects. Special emphasis is laid on suspensions that are driven into a nonequilibrium steady state by pumping the solvent through semipermeable...

We present a general theorem for the force multipole moments of arbitrary order induced in a spherically symmetric particle immersed in a fluid whose motion satisfies the linear Navier-Stokes equation for steady incompressible viscous flow. The multipole moments are expressed in terms of the...
