Viscoelasticity of vibrated granular suspensions

Abstract: Published by the The Society of RheologyArticles you may be interested in Rheology of viscoelastic suspensions of spheres under small and large amplitude oscillatory shear by numerical simulations J. Rheol. 57, 813 (2013); 10.1122/1.4798626 Rheology of concentrated carbon nanotube suspensions SynopsisWe propose, in this paper, a model for predicting the rheological response of both vibrated and sheared 3D granular suspensions in stationary and nonstationary conditions. The major assumption of this model is the… Show more

“…3), σ remains constant untilγ ≈ 1 s −1 and then increases with it. A typical yield stress behavior is observed for the studied suspension, in agreement with previous results [15,19]. The bulk flow curve follows the Herschel-Bulkley law σ = σ f + kγ n , with the values k = 16.9 Pa s n , n = 0.71, and σ f = 105.32 Pa. A frictional stress can be defined as σ f = μP g , with μ = 0.5 ± 0.1 the intergrain friction coefficient and P g the average granular pressure given by [11]…”

“…Vibratory solutions are often used in these industries to control the transport, the storage, or the mixing properties of the granular materials. Recent works have focused on the influence of vibrations on the rheology of granular flows in confined configurations [1][2][3][4]. The present work focuses on free surface flows properties of a beads assembly when both vibrations and gravity act, and on the influence of the basal friction.…”
