Diffusion and Mass Transfer
Autor James S. Vrentas, Christine M. Vrentasen Limba Engleză Hardback – 12 dec 2012
The book first covers the five elements necessary to formulate and solve mass transfer problems, that is, conservation laws and field equations, boundary conditions, constitutive equations, parameters in constitutive equations, and mathematical methods that can be used to solve the partial differential equations commonly encountered in mass transfer problems. Jump balances, Green’s function solution methods, and the free-volume theory for the prediction of self-diffusion coefficients for polymer–solvent systems are among the topics covered. The authors then use those elements to analyze a wide variety of mass transfer problems, including bubble dissolution, polymer sorption and desorption, dispersion, impurity migration in plastic containers, and utilization of polymers in drug delivery. The text offers detailed solutions, along with some theoretical aspects, for numerous processes including viscoelastic diffusion, moving boundary problems, diffusion and reaction, membrane transport, wave behavior, sedimentation, drying of polymer films, and chromatography.
Presenting diffusion and mass transfer from both engineering and fundamental science perspectives, this book can be used as a text for a graduate-level course as well as a reference text for research in diffusion and mass transfer. The book includes mass transfer effects in polymers, which are very important in many industrial processes. The attention given to the proper setup of numerous problems along with the explanations and use of mathematical solution methods will help readers in properly analyzing mass transfer problems.

Recenzii
"Finally a text which integrates in an easily understandable and logical fashion the coupled nature of the equations of change with respect to multicomponent mass transfer and its constitutive equations."
—William H. Velander, University of Nebraska, Lincoln
"The book begins with a description of conservation laws, boundary conditions and constitutive equations…presents a mathematical treatment not covered in other similar books. This is a modern approach to transport phenomena. The unique feature of the book is the treatment of several topics, such as sorption, chromatography, and viscoelastic diffusion."

Descriere
Presenting diffusion and mass transfer from both engineering and fundamental science perspectives, this book offers a comprehensive summary of the theory and applies that theory to obtain detailed solutions to a wide variety of problems. It covers conservation laws and field equations, boundary conditions, constitutive equations, parameters in constitutive equations, and mathematical solution methods including Green’s functions. The authors pay particular attention to polymer mass transfer, and they also discuss the free-volume theory for prediction of self-diffusion coefficients. Problems analyzed include bubble dissolution, impurity migration in plastic containers, and drug delivery using polymers.
