Elastohydrodynamics of a sliding, spinning and sedimenting cylinder near a soft wall
Elastohydrodynamics of a sliding, spinning and sedimenting cylinder near a soft wall
We consider the motion of a fluid-immersed negatively buoyant particle in the vicinity of a thin compressible elastic wall, a situation that arises in a variety of technological and natural settings. We use scaling arguments to establish different regimes of sliding, and complement these estimates using thin-film lubrication dynamics to …
