Mobile particulate systems involve the mechanics, flow and transport properties of mixtures of fluids and solids. These systems are intrinsic to the rheology of emulsions and suspensions, flocculation and aggregation, sedimentation and fluidization, flow of granular media, nucleation and growth of small particles, segregation, attrition and solidification processes. Its diversity means that the area has been studied by a number of different disciplines (such as chemical or civil engineering, mechanics, hydrodynamics, geophysics, condensed matter and statistical physics). This book features general, orientational lectures and advanced topics, covering state-of-the-art approaches to the study of suspensions, fluidized beds, sedimentation and granular flows.
