Yielding and flow in aggregated particulate suspensions
Peter J. Scales, Shane P. Usher, Maria Barmar Larsen +4
A simple and popular constitutive model used to describe the compressional strength of a consolidating strongly cohesive particulate gel is tested further with new experimental dat…
Dynamic and rate-dependent yielding in model cohesive suspensions
Richard Buscall, Peter J. Scales, Anthony D. Stickland +3
An experimental system has been found recently, a coagulated CaCO3 suspension system, which shows very variable yield behaviour depending upon how it is tested and, specifically, a…
Correction of Wall Adhesion Effects in Batch Settling of Strong Colloidal Gels
Daniel R. Lester, Richard Buscall
The batch settling test is widely used to estimate the compressive rheology of strongly flocculated colloidal suspensions, in particular the compressive yield strength and hydrauli…
The yielding of concentrated cohesive suspensions can be deformation rate dependent
Richard Buscall, Peter J. Scales, Anthony D. Stickland +4
The yielding of concentrated cohesive suspensions can be deformation-rate dependent. One consquence of this is that a single suspension can present in one several different ways, d…
Correction of Wall Adhesion Effects in the Centrifugal Compression of Strong Colloidal Gels
Richard Buscall, Daniel R. Lester
Several methods for measuring the compressive strength of strong particulate gels are available, including the centrifuge method, whereby the strength as a function of volume-fract…
The effect of premature wall yield on creep testing of strongly-flocculated suspensions
Anthony D. Stickland, Ashish Kumar, Tiara E. Kusuma +4
Measuring yielding in cohesive suspensions is often hampered by slip at measurement surfaces. This paper presents creep data for strongly-flocculated suspensions obtained using van…
The non-monotonic shear-thinning flow of two strongly cohesive concentrated suspensions
Richard Buscall, Tiara E. Kusuma, Anthony D. Stickland +4
The behaviour in simple shear of two concentrated and strongly cohesive mineral suspensions showing highly non-monotonic flow curves is described. Two rheometric test modes were em…
Wall Adhesion and Constitutive Modelling of Strong Colloidal Gels
Daniel R. Lester, Richard Buscall, Anthony D. Stickland +1
Wall adhesion effects during batch sedimentation of strongly flocculated colloidal gels are commonly assumed to be negligible. In this study in-situ measurements of colloidal gel r…
The relationship between the compressional and shear strengths of poroelastic colloidal gels
Richard Buscall
Strong particulate gels are widely believed to behave poroelastically in compression, e.g. in sedimentation, even though they consolidate irreversibly because of the stickiness of…
Letter to the Editor: Wall slip in dispersion rheometry
Richard Buscall
Whereas our understanding of the role and mechanism of wall slip has improved substantially over the last decade or two, it is still common to see papers on disperse systems appear…
