Preface
part, they are mainly introduced to the principle of similarity, flow visualization, and measurement technology; in the wind tunnel and water tunnel
equipment part, they are introduced to the development and application of
wind tunnel and water tunnel equipment; in the flight mystery and aerodynamics principles part, they are mainly introduced to the flight cognition,
flight principle, the function of aircraft components, etc.; in the personages
of fluid mechanics part, they are introduced to the role and main contribution of famous scientists in the development of fluid dynamics, including
Archimedes, Da Vinci, Galileo, Newton, Leibniz, Bernoulli, Euler, Lagrange,
Helmholtz, Stokes, Reynolds, Mach, etc.
In the process of material selection and discussion, this book starts with the
intuitive and understandable concepts, combines scientific knowledge with
historical development, and introduces the development of fluid mechanics
in a simple and understandable language.
This book has been reviewed by Prof. Wei Qingding who is from the
College of engineering of Peking University and Prof. Zhu Keqin who is from
the School of aerospace engineering of Tsinghua University. I would like to
express my deep gratitude for the important modifications and suggestions.
The process of writing this book was greatly supported by the teachers
and students of the Lu Shijia laboratory of Beihang University. I would like
to express my heartfelt thanks to Dr. Liu Yuan, Dr. Ren Shuili, Dr. Zheng
Yunlong, Dr. Guo Zhifei and Dr. Lu Weishuang from Lu Shijia laboratory
for the translation of this book into English.
The theory of fluid mechanics is rigorous and widely used, which is difficult for the compilation of general introduction. This book covers three
branches: theory, experiment, and numerical simulation. In addition, there
are many industrial applications. Due to the limited space, this book cannot
give a comprehensive introduction. Here, aerodynamics and hydrodynamics
are mainly selected as representatives. Due to the limited knowledge and
energy, the systematization of the book is far from enough. I have been deeply
disturbed by the fact that mistakes cannot be avoided. I am very grateful to
you for your criticism and correction.
