“…This can be interpreted in terms of the decrease in adhesion that is predicted by a number of capillary bridge models as the volume of liquid between a sphere and a f lat plate increases, e.g. [26,27]. The principle can be understood in terms of the reduction in Laplace pressure inside the bridge as the radius of curvature increases.…”

“…Comprehensive details on the liquid bridge force can be found in a study by Mikami et al 26 and others. [27][28][29][30] Derivation of the SPA model First, let us consider a bed of particles and name this bed the original system, which contains original particles i of diameter d p , as shown in Figures 1a,c. These particles are grouped together in which their size, density, and chemical composition are similar.…”

in Wiley Online Library (wileyonlinelibrary.com).The similar particle assembly (SPA) model proposed for large-scale discrete element method simulation was validated. The SPA model describes the scaling law for the motion of particles in an assembly, which is derived from the equation of motion of a particle. In the SPA model, particles with similar physical or chemical properties are represented by a single particle, which is called the representative particle. The local assembly of particles in the original bed is supposed to be maintained in the bed with the representative particles. The SPA model was validated by numerical simulations of a 2D fluidized bed of noncohesive and cohesive particles. Using the SPA model, the flow behavior of the representative particles of a certain magnification can be made similar to that of the original particles with significantly less computational load. A good approximation of bubble size distribution between the SPA bed and the original bed was obtained.

“…The interaction between two solid spheres linked together by a capillary bridge is a classical problem [31][32][33] with practical applications ranging from spore dispersal from plants [34,35] to the formation of micro-particle clusters [36]. Assuming a perfectly wetting sphere, the force between the spheres linked together by a bridge of volume Ω can be written, with the notations of figure 3, as…”

Fragmentation as an aggregation process: the role of defects

A cohesive object will eventually break into fragment when experiencing a strong deformation, during an impact for instance. Using necklaces of cohesive magnetized spheres suddenly expanded, we have shown that the fragmentation of this one-dimensional material results from an inverse aggregation cascade (Vledouts et al. 2015 Proc. R. Soc. A 471, 20150678. (doi:10.1098/rspa.2015). Here, we explore a variant of this process by changing the force law between the attracting spheres, using hydrogel beads linked by capillary bridges. We also investigate the role of (weak) defects in the cohesion strength and the consequences of a distribution of forces between the beads. It is found that fragment do form by a cascade of aggregations, which is interrupted earlier when the force disorder is stronger.
