Summary

Students of the subject will be introduced to fundamental laws and described parameters needed to a mathematic and physical description of a bulk solid behavior. Especially, a core of the subject will be turned to a storage system proposal. Latest knowledge of the rapidly growing branch: nanotechnology will be presented here also. There will be demonstrated measurement methods following interpretation of measured values in the subject. Ideal bulk solid; Definition of bulk solids state; Difference between fundamental material states; Bulk solids logistics; Criteria of transport/Processing system choice for Bulk solids. Granulometry and Morphology, and methods and theory of their assessment, including mathematical models, eg. Gauss, RRSB, Logarithmic Distribution and so on. Bulk solid Properties and Their Description; Flow influence; Flow pattern size and their development; Jenike Shear Machine principle and its equation; Rotary Shear Machine; Another shear machine construction; Interpretation of measured values; Mechanical-Physical Property definition. Particulate Material Constitution for the Bulk Solid Application; Methods of angle of internal friction measurement and its interpretation including energy concept; Partial physical magnitude influence ratio to bulk solid mechanical-physical property. Definition of Inter-Particle Bindings; Ratio of individual physical and geometrical property influence to mechanical-physical properties of Bulk solids, eg. moisture, shape, mechanical and electrical bindings, Roscoe’s diagram and its design and principle, applications. Models of Pressure State Distribution; Models of bulk solid pressure development; General model of bulk solid pressure distribution; Usual and state-of –the art of pressure modeling methods of Bulk solids; Method of pressure distribution solution for Bulk solids according to Janssen’s, Rankin’s and Pascal’s theories. Motion of Bulk Solid Particulates in Assembly Constitution; 1st and 2nd of displacement mechanism; Ideal bulk solids and their deeper relations; Piston flow mechanism and its definition and description including edge conditions; Laminar flow mechanism and its definition and description including edge conditions. Speed Outlet Out of Vessel; Pressure peak and its model creation incl. technical conclusions. Pulsating character of Bulk solid flow; Own and wall frequency.
