Abstract:The rheology of the mixtures is remarkably similar to the monodisperse suspensions for most applied shear stresses. Yield stresses and the general flow curves for all mixtures studied followed the same scaling on the elastic modulus as the monodisperse suspensions. The mixtures display substantial differences in the shear thickening regime. Catastrophic shear thickening is observed, however, the mixtures shear thicken at much lower reduced shear stresses compared to monodisperse suspensions, sharply diminishing the processing window of these suspensions.
