| Description |
The effect of rotational Brownian motion on the rheology of a dilute suspension of dipolar spheroids
in a simple shear flow under the action of an external force field, is investigated through a
generalized Langevin equation approach. The force field is assumed to be either constant or
periodic. In the case of constant external fields earlier results in the literature are reproduced, while
for the case of periodic forcing certain parametric regimes corresponding to weak Brownian
diffusion are identified where the rheological parameters evolve chaotically and settle onto a low
dimensional attractor. The response of the system to variations in the strengths of the force field and
diffusion is also analyzed through numerical experiments. These results correspond to the region of
weak Brownian motion where usual methods render the problem intractable.
