Notes:
We consider a Hamiltonian for a complex fluid. The linear excess bulk viscosity due to a spatially varying order parameter is investigated. We calculate the dependence of the excess viscosity Δη, on the fundamental parameters d and ξ, everywhere within the disordered phase (d being the domain size of water or oil and ξ being the correlation length between domains). It is found that there is a crossover region in the isotropic disordered phase of this model. More specifically, in the structured region of the isotropic disordered phase Δη grows as ξ3 in the vicinity of disordered-lamellar transition. This is quite distinct from the behavior of the excess viscosity in the unstructured region where Δη grows as ξ in the vicinity of the order-disorder transition.
