Fractals play an important role in modeling natural phenomena and engineering processes. And fractals have a close connection to the concepts of chaotic dynamics. This monograph presents definitions, concepts, notions and methodologies of both spatial and temporal fractals. It addresses students and researchers in chemistry and in chemical engineering. The authors present the concepts and methodologies in sufficient detail for uninitiated readers. They include many simple examples and graphical illustrations. They outline some examples in more detail: Perimeter fractal dimension of char particles, surface fractal dimension of charcoal; fractal analysis of pressure fluctuation in multiphase flow systems. Readers who master the concepts in this book, can confidently apply them to their fields of interest.Hinweis: Dieser Artikel kann nur an eine deutsche Lieferadresse ausgeliefert werden.
The concepts of spatial and temporal fractals are applied to many scientific and engineering problems. The authors are professors in chemical engineering and statistics. They introduce fractals without mathematical rigor for students and practitioners. Many simple examples illustrate the book.
