Phenomenology of hydrodynamic interactions in suspensions of weakly deformable particles

چکیده

What is the influence of hydrodynamic interactions on the equations of motion of a suspension of deformable particles ? We propose here a qualitative answer for a neutrally-buoyant suspension with weak particle deformations. We show that the influence of the neighbouring particles can be pictured by only two functions of the particle volume fraction when quadratic deformation terms are neglected. The influence of the viscosity ratio is completely determined by assuming that the particles deform homogeneously. It is suggested that Hand’s equations are not the most convenient starting point for discussing hydrodynamic interactions. J.

Collective diffusion in sheared colloidal suspensions

Collective diffusivity in a suspension of rigid particles in steady linear viscous flows is evaluated by investigating the dynamics of the time correlation of long-wavelength density fluctuations. In the absence of hydrodynamic interactions between suspended particles in a dilute suspension of identical hard spheres, closed-form asymptotic expressions for the collective diffusivity are derived ...

The growth of concentration fluctuations in dilute dispersions of orientable and deformable particles under sedimentation

Theory and numerical simulations are used to investigate the concentration fluctuations and the microstructure in dilute sedimenting suspensions of orientable and deformable particles at zero Reynolds number. The case of orientable particles is studied using prolate and oblate spheroids, while viscous droplets in the small deformation regime illustrate the effects of deformability. An efficient...

Simulation method of colloidal suspensions with hydrodynamic interactions: fluid particle dynamics

We develop a new simulation method of colloidal suspensions, which we call a "fluid particle dynamics" (FPD) method. This FPD method, which treats a colloid as a fluid particle, removes the difficulties stemming from a solid-fluid boundary condition in the treatment of hydrodynamic interactions between the particles. The importance of interparticle hydrodynamic interactions in the aggregation p...

Short–time rotational diffusion in monodisperse charge–stabilized colloidal suspensions

We investigate the combined effects of electrostatic interactions and hydrodynamic interactions (HI) on the short–time rotational self– diffusion coefficient Dr s in charge–stabilized suspensions. We calculate Dr s as a function of volume fraction φ for various effective particle charges and various amounts of added electrolyte. The influence of HI is taken into account by a series expansion of...

Dynamic simulation of hydrodynamically interacting particles

A general method for computing the hydrodynamic interactions among N suspended particles, under the condition of vanishingly small particle Reynolds number, is presented. The method accounts for both near-field lubrication effects and the dominant many-body interactions. The many-body hydrodynamic interactions reproduce the screening characteristic of porous media and the ‘effective viscosity ’...
