0000023816 00000 n J. Fluid Mech. Morris has analyzed two distinct forms of particle migration, one induced by the bulk rheological influence of the particles and known as shear-induced migration, and one driven by inertia.

Morris 2009 A review of microstructure in concentrated suspensions and its implications for rheology and bulk flow. A robust system-scale heat transfer model for the packed bed is developed and accounts for wall heat transfer and intra-particle diffusion effects. Math. The method include spray drying a solution containing a polyamide to form polyamide particles having an average diameter of between about 0.5 μm and about 10 μm and at least about 85% of the polyamide particles having a diameter distribution of no more than about 1.5 μm.The discontinuous shear thickening (DST) of dense suspensions is a remarkable phenomenon in which the Phil.

Such shear-jammed states are fragile, i.e., they are not stable against applied stresses that are incompatible with the stress imposed to create them. Au cours d'un seul mode, les comportements de déstabilisation ont été observés: déclenchement de l’instabilité, éjection de plumes, retrait des particules, resuspension et sédimentation.
