WebJan 1, 2001 · This paper describes an extension of classic thermodynamics to granular assemblies subjected to an energy flux through the granular assembly. By means of a Carnot engine, the granular temperature and entropy of a particle assembly is defined. The principal value of introducing the notion of granular temperature is that it defines a … A granular material is a conglomeration of discrete solid, macroscopic particles characterized by a loss of energy whenever the particles interact (the most common example would be friction when grains collide).
