Tangential Forces Govern the Viscous-Inertial Transition in Dense Frictional Suspensions

Author(s): Sudarshan Konidena, Franco Tapia, Alireza Khodabakhshi, Élisabeth Guazzelli, Pascale Aussillous, and Bernhard Vowinckel We present particle-resolved simulations of dense frictional suspensions undergoing the viscous-inertial transition using pressure-imposed rheology. By varying the fluid viscosity, shear rate, and granular pressure, we demonstrate that the transition occurs at a Stokes number of $≈8$ (close to the v… [Phys. Rev.
