Rising and sinking intruders in dense granular flows
We computationally determine the net bed force on single spherical intruder particles in dense granular flows as a function of particle size, particle density, shear rate, overburden pressure, and gravity. A simple buoyancy-like scaling law is recovered (analogous to that in fluids), but with a scal...
