Mechanical and Solid-Fluid Operations

The text thoroughly discusses the fundamentals of flow resistance over a solid body, the frictional resistance of flow through a granular bed, and the flow phenomena of particles, which are essential requirements for solid-fluid operations in various process units, especially in mineral and chemical industries. It elucidates the fundamentals of drag force on a solid, terminal velocity of the particle, sedimentation, slurry mixing, fluidization phenomena and froth flotation. This book: - Presents a discussion of theoretical principles and illustrative examples to help readers learn how to operate, optimize, and innovate particle processing technologies - Covers the fundamentals of drag force on a solid, terminal velocity of the particle, and sedimentation (hindered settling) - Explain the basic law and terminology of fluid flow through a granular bed, mixing characteristics in an agitator, and its standard design - Illustrates systematic and comprehensive understandings of the fundamental phenomena of fluidization and the basic principles and kinetics of froth flotation - Includes ancillary material such as numerical problems, review questions, multiple choice questions, and exercises at the end of each chapter It is primarily written for senior undergraduates, graduate students, and academic researchers in chemical engineering, mechanical engineering, environmental engineering, industrial engineering, manufacturing engineering, and chemistry.
