S-shaped flow curves of shear thickening suspensions: direct observation of frictional rheology.
We study the rheological behavior of concentrated granular suspensions of simple spherical particles. Under controlled stress, the system exhibits an S-shaped flow curve (stress vs shear rate) with a negative slope in between the low-viscosity Newtonian regime and the shear thickened regime. Under controlled shear rate, a discontinuous transition between the two states is observed. Stress visua...

متن کاملRheology of suspensions of small fibres in turbulent channel flow .
A stochastic simulation (Monte-Carlo-) method for the dynamics and rheological behaviour of small Brownian axisymmetric particles or fibres in a Newtonian solvent is tested and verified. The stress field due to the presence of the particles in a sheared or strained flow field is related to the conformation of the particles via the second and fourth moments of the conformation distribution funct...
متن کاملRheology of Microfibrillated Cellulose Suspensions in Pressure-driven Flow
Rheology of Microfibrillated Cellulose (MFC) suspensions is useful for designing equipment to transport, mix, or process them. Pressure-driven flow behavior is particularly important for MFC suspensions if they are to be pumped, extruded or coated. Herein, we report use of slot and pipe geometries for determination of MFC suspension rheology and compare the results to boundary-driven flows. MFC...
متن کاملFault rheology beyond frictional melting.
During earthquakes, comminution and frictional heating both contribute to the dissipation of stored energy. With sufficient dissipative heating, melting processes can ensue, yielding the production of frictional melts or "pseudotachylytes." It is commonly assumed that the Newtonian viscosities of such melts control subsequent fault slip resistance. Rock melts, however, are viscoelastic bodies, ...
