Boundary compliance selects heterogeneous dynamics in shear-thickening suspensions
Li-Xin Shi, Meng-Fei Hu, Song-Chuan Zhao
The mechanical properties of confining boundaries can fundamentally alter the flow behaviour of shear-thickening suspensions. We study a dense cornstarch suspension sheared beneath…
Boundary conditions alter density and stress fluctuations in shear-thickening suspensions
Meng-Fei Hu, Song-Chuan Zhao
Discontinuous shear thickening (DST) in dense suspensions is accompanied by significant fluctuations in stress at a fixed shear rate. In this work, normal stress fluctuations are s…
Freezing delay of a drop impacting on a monolayer of cold grains
Yudong Li, Song-Chuan Zhao
We investigate a subfreezing droplet impact scenario in a low-humidity environment, where the target is a cold granular monolayer. When the undercooling degree of targets passes a…
Localized jammed clusters persist in shear-thickening suspension subjected to swirling excitation
Li-Xin Shi, Song-Chuan Zhao
We investigate the dynamic evolution of heterogeneity in shear-thickening suspensions subjected to swirling excitation with a free surface. The uniform state of such a system may l…
Cold granular targets slow the bulk freezing of an impacting droplet
Song-Chuan Zhao, Hao-Jie Zhang, Yudong Li
When making contact with an undercooled target, a drop freezes. The colder the target is, the more rapid the freezing is supposed to be. In this research, we explore the impact of…
Emergence of a hexagonal pattern in shear-thickening suspensions under orbital oscillations
Li-Xin Shi, Meng-Fei Hu, Song-Chuan Zhao
Dense particle suspension under shear may lose its uniform state to large local density and stress fluctuations, which challenge the mean-field description of the system. Here, we…
Collective motion of granular matter subjected to swirling excitation
Song-Chuan Zhao, Thorsten Pöschel
A two-dimensional granular packing under horizontally circular shaking exhibits various collective motion modes depending on the strength of the oscillation and the global packing…
Impact cratering in sand: Comparing solid and liquid intruders
Rianne de Jong, Song-Chuan Zhao, Diana Garcia-Gonzalez +2
How does the impact of a deformable droplet on a granular bed differ from that caused by a solid impactor of similar size and density? Here, we experimentally study this question a…
Spontaneous formation of density waves in granular matter under swirling excitation
Song-Chuan Zhao, Thorsten Pöschel
We study here the spontaneous clustering of a submonolayer of grains under horizontal circular shaking. The clustering of grains occurs when increasing the oscillation amplitude be…
3D Printed Actuators: Reversibility, Relaxation and Ratcheting
Song-Chuan Zhao, Mariska Maas, Kaspar Jansen +1
Additive manufacturing strives to combine any combination of materials into three dimensional functional structures and devices, ultimately opening up the possibility of 3D printed…
Liquid-grain mixing suppresses droplet spreading and splashing during impact
Song-Chuan Zhao, Rianne de Jong, Devaraj van der Meer
Would a raindrop impacting on a coarse beach behave differently from that impacting on a desert of fine sand? We study this question by a series of model experiments, where the pac…
Crater formation during raindrop impact on sand
Rianne de Jong, Song-Chuan Zhao, Devaraj van der Meer
After a raindrop impacts on a granular bed, a crater is formed as both drop and target deform. After an initial, transient, phase in which the maximum crater depth is reached, the…
Raindrop impact on sand: a dynamic explanation of crater morphologies
Song-Chuan Zhao, Rianne de Jong, Devaraj van der Meer
As a droplet impacts on a granular substrate, both the intruder and the target deform, during which the liquid may penetrate into the substrate. {These three aspects together disti…
Measuring the configurational temperature of a binary disc packing
Song-Chuan Zhao, Matthias Schröter
Jammed packings of granular materials differ from systems normally described by statistical mechanics in that they are athermal. In recent years a statistical mechanics of static g…
Correlation between Voronoi volumes in disc packings
Song-Chuan Zhao, Stacy Sidle, Harry L. Swinney +1
We measure the two-point correlation of free Voronoi volumes in binary disc packings, where the packing fraction ranges from 0.8175 to 0.8380. We observe short-ranged…
