542-0056/01 – Mechanics and properties of particulate materials (MVPH)

The mechanics and properties of particulate matter is the subject that is constantly evolving and naturally integrates new technical knowledge. At the present stage it is mainly the knowledge of the structure and properties of particulate matter and the digital shift. Bulk solids materials were taken in history as a part of fluid mechanics, mechanics of mass points, continuum. The separate scientific discipline is currently being intensively developed. The aim of the course material is loose introduction to the more general approach to describe the processes occurring in the bulk masses and their applications in transport, storage and production. Such a general concept of bulk materials, which are studied and described changes in the form particulate materials in the form of mathematical and physical models is necessary for ongoing intensive development and growth of information industry.

Bulk materials (generally, particle systems) are now in technical and scientific the most dynamically developing discipline. The literature even a discussion on the definition of a new phase, because their properties and physical manifestations differs from all known forms of matter. 40% of all funds for Research of the European Union towards the area of ​​bulk materials (micrometer and nanometric particles). In this course, students will be bulk familiar with the general approach to describe the processes occurring in bulk Fuels and their applications in transport, storage and production. Such a general concept of bulk materials, which are studied and described changes in the form particulate materials in the form of mathematical and physical models is necessary for ongoing intensive development and growth of information industry. This point of view is necessary for understanding new information and work on innovative entrepreneurship. This allow students the idea of ​​the possibilities of traditional practices and development directions of the field and timely response to possible developments. The Course changes will be characterized by bulk properties, such as accompanying conditions of transport, production and storage. On the contrary, the changes in mechanical physical properties of bulk materials in time, you can identify the typical signs and traffic process that preceded them. The lectures are devoted to the description of mechanical-physical and geometrical properties of bulk materials and interpretation of changes in mechanical processes. Students will acquire sufficient information for the proper choice of transport and storage depending on the characteristics of the manufacturing process of bulk materials for many applications (such as cement, wood chips, gravel, plastic granules, cocoa, coal powder, carbon black, wheat).

In the course of teaching, students realize three basic laboratory measurements - friction parameters, granulometry, initial mass parameters of particulate matter. Measurements are included in the credit. At the seminars the students will be acquainted with the solution of practical applications and the credit is based on hand in assignments. The overall knowledge verification is realized in the written part of the exam, which the student defends orally.
