For undergraduate chemical engineering majors at the junior level.
This text introduces the fundamental concepts of transport phenomena and enables students to translate physical phenomena into mathematical terms. All the basic principles of transport phenomena are introduced with mathematical complexity kept to minimum.
Orients course to the simplest of transport processes, employing differential equation solver to solve complex transport problems. Ex.___
Students learn WHY the various dimensionless parameters appear in empirical correlations. Ex.___
Enables students to see the connection between transport phenomena and macroscopic calculations, thus eliminating the tendency to treat the two approaches as separate subject matter. Ex.___
Students see that transfer coefficients are defined, dimensionless dependent variables that can be either calculated (simple flow systems) or measured (complex flow systems). Ex.___
I. MOLECULAR TRANSPORT.1. The Nature of Transport Phenomena.
II. CONVECTIVE TRANSPORT.8. Convective Transport in Laminar Flow.
III. MACROSCOPIC CALCULATIONS.11. Macroscopic Calculations: Momentum Transport.
This book is a true introduction to transport phenomena that presents all basic principles with a minimum of mathematical complexity. Readers will only need to know the basics of differential equations, and how to use a differential equation solver such as Matlab or ACSL.
Professor William J. Thomson emphasizes the formulation of differential equations to describe physical problems, helping readers understand what they are doing-and why. The solutions are either simple (separable, linear second order) or derivable with a differential equation solver.
Thomson begins with a detailed introduction to molecular transport, including the basic underlying laws, one-dimensional molecular energy transport, molecular mass and momentum transport principles, and transport coefficients. Each major similarity analysis technique is covered, including dimensionless groups in molecular transport, dimensionless differential transforms, and similarity transforms.
In Part II, Thomson reviews convective transport, presenting a straightforward description of turbulence, and introducing the fundamental concept of transfer coefficients. Building on previous coverage, he then addresses the macroscopic calculation issues associated with momentum, heat, and mass transfer-enabling readers to solve even complex gas absorption and cooling tower problems.
