Preface
If modern civilization originated from the rise and development of the
mechanical industry, the combination of fluid mechanics and the mechanical
industry has played a decisive role. It can also be said that fluid mechanics
is a bright pearl on the crown of modern mechanical industry. From the
ancient hydraulic machinery to the birth of the most complex modern aeroengine, it is closely related to the development of fluid mechanics. It can also
be said that fluid mechanics is involved in water turbines, steam turbines,
gas turbines, expanders, wind turbines, pumps, fans, ventilators, compressors,
hydraulic couplers, hydraulic torque converters, pneumatic tools, pneumatic
motors, hydraulic motors, and various fluid transport and control equipment, all of which use the fluid as working fluid to convert energy. Therefore, there is no doubt that fluid mechanics is the most active professional
basic subject in the mechanical industry, and it is also a professional basic
course offered by the technological universities. In order to stimulate the
learning interest of beginners and facilitate the understanding of the basic
knowledge and development of the law of fluid mechanics, I tried a compilation mode that combines scientific knowledge with the human history of
fluid mechanics in the form of biography and popular science. There are
eight chapters in the book, namely, basic theories of fluid mechanics, aerodynamics, hydrodynamics, computational fluid dynamics, experimental fluid
dynamics, wind tunnel and water tunnel equipment, flying mystery and aerodynamics principles. In the fundamentally theoretical part, readers are introduced to the development and application of theory; in the experimental
