Correlated particle dynamics in concentrated quasi-two-dimensional suspensions
Correlated particle dynamics in concentrated quasi-two-dimensional suspensions
We investigate theoretically and experimentally how the hydrodynamically correlated lateral motion of particles in a suspension confined between two surfaces is affected by the suspension concentration. Despite the long range of the correlations (decaying as 1/r2 with the inter-particle distance r), the concentration effect is present only at short inter-particle …
