Darcy-Reynolds forces during intrusion into granular-fluid beds

  title={Darcy-Reynolds forces during intrusion into granular-fluid beds},
  author={Joshua Strader and Neil Causley and Joshua A. Dijksman and Abram H. Clark},
We experimentally study intrusion into fluid-saturated granular beds by a free-falling sphere, varying particle size and fluid viscosity. We test our results against Darcy-Reynolds theory, where the deceleration of the sphere is controlled by Reynolds dilatancy and the Darcy flow resistance. We find the observed intruder dynamics are consistent with Darcy-Reynolds theory for varied particle size. We also find that our experimental results for varied viscosity are consistent with DarcyReynolds… Expand

Unifying suspension and granular rheology.
Dense suspension and granular media are unified under a common framework and the results are shown to be compatible with classical empirical models of suspension rheology and provide a clear determination of constitutive laws close to the jamming transition. Expand
Depth-dependent resistance of granular media to vertical penetration.
The quasistatic friction force acting on intruders moving downwards into a granular medium is measured, set by a friction coefficient, hydrostatic pressure, projectile size and shape, and a dimensionless proportionality constant. Expand
Transition from the viscous to inertial regime in dense suspensions.
Varying the interstitial fluid viscosities, the Newtonian and Bagnoldian regimes are recovered and it is shown that the two rheological regimes can be unified as a function of a single dimensionless number, by adding the contributions to the dissipation at a given volume fraction. Expand
Local Rheology Relation with Variable Yield Stress Ratio across Dry, Wet, Dense, and Dilute Granular Flows.
This work carries out extensive simulations of granular flows, including wet and dry conditions, various geometries and driving mechanisms (boundary driven, fluid driven, and gravity driven), many of which are not captured by standard rheology models. Expand
Power-Law Scaling of Early-Stage Forces during Granular Impact.
The insensitivity of the results to many system details suggests that they may also apply to impacts into similar materials like foams and emulsions. Expand
Discontinuous shear thickening of frictional hard-sphere suspensions.
It is shown that contact friction is essential for having DST, and above a critical volume fraction, the existence of two states: a low viscosity, contactless (hence, frictionless) state, and a high Viscosity frictional shear jammed state. Expand
Discontinuous shear thickening without inertia in dense non-Brownian suspensions.
It is shown that reasonable assumptions about contact proliferation predict two distinct types of DST in the absence of inertia; the first occurs at densities above the jamming point of frictional particles; here, the thickened state is completely jammed and (unless particles deform) cannot flow without inhomogeneity or fracture. Expand
Impact-activated solidification of dense suspensions via dynamic jamming fronts
A model for the dynamic solidification and its effect on the surrounding suspension that reproduces the observed behaviour quantitatively is developed and suggests that prior interpretations of the impact resistance as dominated by shear thickening need to be revisited. Expand
Granular impact and the critical packing state.
Postimpact crater morphology identifies the critical packing state ϕcps, where sheared grains neither dilate nor consolidate, and indicates an associated change in spatial response. Expand
Rheology of dense granular suspensions
Suspensions are composed of mixtures of particles and fluid and are omnipresent in natural phenomena and in industrial processes. The present paper addresses the rheology of concentrated suspensionsExpand
