The text is divided into two parts, which can be used for teaching a two-term course. Part I covers the balance equation in the context of diffusive transport—momentum, energy, mass, and charge. Each chapter adds a term to the balance equation, highlighting that term's effects on the physical behavior of the system and the underlying mathematical description. Chapters familiarize students with modeling and developing mathematical expressions based on the analysis of a control volume, the derivation of the governing differential equations, and the solution to those equations with appropriate boundary conditions.
Part II builds on the diffusive transport balance equation by introducing convective transport terms, focusing on partial, rather than ordinary, differential equations. The text describes paring down the microscopic equations to simplify the models and solve problems, and it introduces macroscopic versions of the balance equations for when the microscopic approach fails or is too cumbersome. The text discusses the momentum, Bernoulli, energy, and species continuity equations, including a brief description of how these equations are applied to heat exchangers, continuous contactors, and chemical reactors. The book also introduces the three fundamental transport coefficients: the friction factor, the heat transfer coefficient, and the mass transfer coefficient in the context of boundary layer theory. The final chapter covers the basics of radiative heat transfer, including concepts such as blackbodies, graybodies, radiation shields, and enclosures. The third edition incorporates many changes to the material and includes updated discussions and examples and more than 70 new homework problems.
Joel L. Plawsky received his BS in chemical engineering from the University of Michigan and his MSCEP and ScD in chemical engineering from the Massachusetts Institute of Technology. After graduation, Joel worked for Corning Inc. in its research division before returning to academia at Rensselaer Polytechnic Institute. He is currently a professor of chemical engineering in the Howard P. Isermann Department of Chemical and Biological Engineering. Joel was a NASA Faculty Fellow in 1999 and 2000 and has had four experiments fly in the microgravity environment of the Space Shuttle and the International Space Station. He is a fellow of the American Institute of Chemical Engineers where he has served as the chairman of the Transport and Energy Processes Division and has received the Institute’s Herbie Epstein Award. Joel serves on the editorial board of Chemical Engineering Communications and is the holder of five patents.
