پیش درآمد کتاب و حل المسائل جریان تراکم ناپذیر
This book is written as a textbook for students beginning a serious study of fluid dynamics, or for students in other fields who want to know the main ideas and results in this discipline. A reader who judges the scope of the book by its title will be somewhat surprised at the contents.
The contents not only treat incompressible flows themselves but also give the student an understanding of how incompressible flows are related to the general compressible case. For example, one cannot appreciate how energy
interactions occur in incompressible flows without first understanding the most general interaction mechanisms.
I subscribe to the philosophy that advanced students should study a subject’s structure, techniques, and results. The beginning chapters are devoted to building the concepts and physics for a general, compressible, viscous fluid flow.
These chapters themselves constitute the fundamentals that one might study in any course concerning fluid dynamics. Beginning with Chapter 6 our study is restricted to fluids that obey Newton’s viscosity law. Only when we arrive at Chapter 10 do we find a detailed discussion of the assumptions that underlie the subject of incompressible flow.
Thus, roughly half the book is fundamentals, and the rest is incompressible flow. Applied mathematicians have contributed greatly to the study of fluid mechanics, and there is a tendency to make a text into a sampler of known mathematical solutions.

A conscious effort was made in writing the book to strike an even balance among physics, mathematics, and practical engineering information. The student is assumed to have had calculus and differential equations; the text then takes on the task of introducing tensor analysis in index notation, as well as various special methods of solving differential equations that have been developed in fluid mechanics.
This includes an introduction to several computer methods and the method of asymptotic expansions. The book places heavy emphasis on dimensional analysis, both as a subject in itself and as an instrument in any analysis of flow problems.
The advanced worker knows many shortcuts in this area, but the student needs to study the foundations and details in order to be convinced that these shortcuts are valid. Vorticity, vortex lines, and the dynamics of vorticity also receive an expanded treatment, which is designed to bring the severe student more information than is customary in a textbook.
It is apparent that advanced workers in fluid mechanics must be able to interpret flow patterns in terms of vorticity as well as in the traditional terms of forces and energy. The study of how changes in the Reynolds number influence flow patterns occupies a large part of the book.
Separate chapters describe flows at low, moderate, and high Reynolds numbers. Because of their practical importance, the complementary subjects of inviscid flows and boundary-layer flows are treated extensively. Introductory chapters on stability and turbulence are also given.
These last two subjects are so large as to constitute separate fields. Nevertheless, a beginning student should have an overview of the rudiments and principles.
