Webis known that a granular jump can be formed, similarly to hydraulic jumps in a supercritical regime. This paper describes a continuum model of steady jumps and propagating bores … WebThe theoretical description of granular materials, or assemblies of macroscopic particles, is a formidable task. Not only are granular materials out of thermal equilibrium, but they are also characterized by dissipative interactions and by static friction. Following a suggestion by S. F. Edwards, researchers
