Shear thinning in non-Brownian suspensions explained by variable friction between particles

Shear thinning in non-Brownian suspensions explained by variable friction between particles

... We propose to explain shear thinning behaviour observed in most concentrated non- Brownian suspensions by variable friction between particles. Considering the low mag- nitude of the forces experienced by ...

Imaging non-Brownian particle suspensions with X-ray tomography: application to the microstructure of Newtonian and visco-plastic suspensions

Imaging non-Brownian particle suspensions with X-ray tomography: application to the microstructure of Newtonian and visco-plastic suspensions

... Abstract A key element in the understanding of the rheological behaviour of suspensions is their mi- crostructure. Indeed, the spatial distribution of particles is known to depend on flow history in suspensions, which ...
