摘要: Abstract The rheology of slightly deformable particles, in particular their dilatant behaviour, has been investigated using waxy maize starch as a ‘model’ suspension. Suspensions such large particles present considerable experimental problems rheological terms that they exhibit phenomena wall slip and sedimentation. These are discussed some detail, along with the methodologies developed to overcome them. Comparisons results hard sphere data literature indicate whilst deformability granules does not play significant role high shear limiting viscosity, transition appear be strongly affected.
