Description

Entropy of Complex Processes and Systems formalizes our understanding of many complex processes, including the development of the methodology of analytical computation of complex processes as applied in many industries, such as ore processing, or more generally, in areas of natural sciences. The adequacy of the results of these calculations is confirmed by numerous experimental data obtained both on pilots and industrial facilities. The book also provides a thorough analysis of the underlying physical foundations of entropy performed from new standpoints that are of interest to theoreticians studying contemporary expositions.

Key Features

  • Provides methodologies for controlling and optimizing complex processes in branches of industry that involve transformation of materials or substances
  • Describes entropy as the universal characteristic of a stochastic process independent of the system
  • Introduces a new definition of entropy specifically related to dynamical phenomena

Readership

Scientists and students in (chemical) engineering sciences dealing with mass random processes and systems. Engineers in chemical technology working in industry dealing with the optimization of complex industrial processes

About the Author

Eugene Barsky

The author, Dr. Eugene Barsky, has been engaged in this subject for 18 years, since 1993. His M.Sc. thesis completed in 1998 was devoted to the development of models of cascade separation of solid materials in flows. His PhD thesis completed in 2001 was devoted to the development of entropy criterion of separation processes optimization. Among dozens of criteria applied, the entropy criterion has proved to be the most unbiased one. Since that time, the author has been developing these topics in depth. He created a number of industrial cascade apparatuses for powders separation and dust collection, wrote about 20 articles, published two books, participated in many scientific congresses and conferences. The material accumulated during 6 recent years is presented in the proposed book.
