;This book is intended to be a text for either a first or a second
course in numerical methods for students in all engineering
disciplines. Difficult concepts which usually pose problems to
students are explained in detail and illustrated with solved
examples. Enough elementary material that could be covered in the
first-level course is included such as methods for solving linear
and nonlinear algebraic equations, interpolation, differentiation,
integration, and simple techniques for integrating ODEs and PDEs
(ordinary and partial differential equations). Advanced techniques
and concepts that could form part of a second-level course include
Gear's method for solving ODE-IVPs (initial value problems),
stiffness of ODE-IVPs, multiplicity of solutions, convergence
characteristics, the orthogonal collocation method for solving
ODEBVPs (boundary value problems) and finite element techniques. An
extensive set of graded problems, often with hints, has been
included. Some involve simple applications of the concepts and can
be solved using a calculator, while several are from real-life
situations and require writing computer programs or use of library
subroutines. Practice on these is expected to build up the reader's
confidence in developing large computer codes.
This text, written as an introduction to fluid mechanics for
students of all engineering disciplines, emphasizes fluid flow
phenomena and their modelling. The level of mathematics is kept at
the minimum so that a student can pay full attention to the
complexities of the fundamental physical concepts and develop a
physical feel of the subject. Common misapplications,
misunderstandings and over-generalizations made by students are
anticipated and cautioned against. Relatively newer and simpler
treatments have been used in several topics such as Euler
acceleration formula, Reynolds transport theorem and Bernoulli
equation, and a new unified treatment of modelling, similitude and
the basis of approximations has been presented. A preview of fluid
flow phenomena in Chapter 1 and an overview in the epilogue are
included. A whole array of applications from diverse engineering
disciplines has been introduced through numerous solved examples
and over five hundred carefully graded problems. In this new
edition, Chapter 9 on Similitude and Modelling has been re-written
so as to make it easier to understand, and suggestions of several
users have been incorporated.
The literature in polymerization reaction engineering has bloomed
sufficiently in the last several years to justify our attempt in
putting together this book. Rather than offer a comprehensive
treatment of the entire field, thereby duplicating earlier texts as
well as some ongoing bookwriting efforts, we decided to narrow down
our aim to step growth polymerization systems. This not only
provides us the lUxury of a more elaborate presentation within the
constraints of production costs, but also enables us to remain on
somewhat familiar terrain. The style and format we have selected
are those of a textbook. The first six chapters present the
principles of step growth polymerization. These are quite general,
and can easily be applied in such diverse and emerging fields as
polymerization applications in photolithography and microelec
tronics. A detailed discussion of several important step growth
polymeriz ations follows in the next five chapters. One could cover
the first six chapters of this book in about six to eight weeks of
a three-credit graduate course on polymerization reactors, with the
other chapters assigned for reading. This could be followed by a
discussion of chain-growth and other polymeriz ations, with which
our material blends well. Alternately, the entire contents of this
book could be covered in a course on step growth systems alone."
