Self-organisation -- the underlying principle and a general formalism
Raphael Blumenfeld
It is proposed that self-organisation (SO) in non-equilibrium systems is governed by a general principle: it emerges when a minute subset of system configurations are exceptionally…
Da Vinci Fluids, catch-up dynamics and dense granular flow
Raphael Blumenfeld, Sam F. Edwards, Moshe Schwartz
We introduce and study a da Vinci Fluid, a fluid whose dissipation is dominated by solid friction. We analyse the flow rheology of a discrete model and then coarse-grain it to the…
Geometric partition functions of cellular systems: Explicit calculation of the entropy in two and three dimensions
Raphael Blumenfeld, Sam F. Edwards
A method is proposed for the characterisation of the entropy of cellular structures, based on the compactivity concept for granular packings. Hamiltonian-like volume functions are…
Granular Matter and the Marginal Rigidity State
R Blumenfeld, S F Edwards, R C Ball
Model experiments are reported on the build-up of granular piles in two dimensions. These show that as the initial density of falling grains is increased, the resulting pile has de…
