Waves, Algebraic Growth, and Clumping in Sedimenting Disk Arrays

An array of spheres descending slowly through a viscous fluid always clumps [J. M. Crowley, J. Fluid Mech. 45, 151 (1971)JFLSA70022-112010.1017/S0022112071003045]. We show that anisotropic particle shape qualitatively transforms this iconic instability of collective sedimentation. In experiment and...
