Densely packed particle raft at vertically vibrated air-water interface
Xiuhe Yan, Tabitha C. Watson, Hongyi Xiao
We investigate the dynamics of a dense raft of millimeter-sized granular particles at a vertically vibrated air-water interface, which displays a rich set of patterns and particle…
Reciprocal swimming in granular media: the role of jamming and swimmer inertia
Amir Nazemi, Hongyi Xiao
We use particle simulations to reveal two distinct propulsion mechanisms for a scallop-like swimmer to propel itself in granular media by reciprocally flapping its wings. Based on…
Reciprocal swimming in viscoelastic granular hydrogels
Hongyi Xiao, Jing Wang, Achim Sack +2
We experimentally study a scallop-like swimmer with reciprocally flapping wings in a nearly frictionless, cohesive granular medium consisting of hydrogel spheres. Significant locom…
Locomotion of a Scallop-Inspired Swimmer in Granular Matter
Hongyi Xiao, Harol Torres, Achim Sack +1
Understanding swimming in soft yielding media is challenging due to their complex deformation response to the swimmer's motion. We experimentally show that a scallop-inspired swimm…
