Book description
The All-in-One Guide to Mass Transport Phenomena: From Theory to Examples and Computation
Mass transfer processes exist in practically all engineering fields and many biological systems; understanding them is essential for all chemical engineering students, and for practitioners in a broad range of practices, such as biomedical engineering, environmental engineering, material engineering, and the like. Mass Transfer Processes combines a modern, accessible introduction to modeling and computing these processes with demonstrations of their application in designing reactors and separation systems.
P. A. Ramachandran’s integrated approach balances all the knowledge readers need to be effective, rather than merely paying lip service to some crucial topics. He covers both analytical and numerical solutions to mass transfer problems, demonstrating numerical problem-solving with widely used software packages, including MATLAB and CHEBFUN. Throughout, he links theory to realistic examples, both traditional and contemporary.
Theory, examples, and in-depth coverage of differential, macroscopic, and mesoscopic modeling
Physical chemistry aspects of diffusion phenomena
Film models for calculating local mass transfer rates and diffusional interaction in gas—solid and gas—liquid reaction systems
Application of mass transfer models in rate-based separation processes, and systems with simultaneous heat and mass transfer
Convective mass transfer: empirical correlation, internal and external laminar flows, and turbulent flows
Heterogeneous systems, from laminar flow reactors, diffusion-reaction models, reactive membranes, and electrochemical reactors
Computations of mass transfer effects in multicomponent systems
Solid—gas noncatalytic reactions for chemical, metallurgical, environmental, and electronic processes
Applications in electrochemical and biomedical systems
Design calculations for humidification, drying, and condensation systems and membrane-based separations
Analysis of adsorption, chromatography, electrodialysis, and electrophoresis
