Preface
Liquid is a solid in the form of water, gas, or air. The most common examples encountered in daily life and engineering applications are water, air, and steam; the second is water vapor. Pumps, compressors, spinning disks (as in computer drives), aircraft, spacecraft, road vehicles, and marine vessels are examples of flow. This book focuses primarily on Newtonian fluids such as water and air because their properties are independent of flow. The theory of fluid flow, also called fluid dynamics, is based on the application of Newton’s laws of motion and the law of conservation of mass. To analyze the flow of gases or vapors in which density changes due to changes in pressure (known as compressible fluids), it is important to consider the laws of thermodynamics, especially the first law in the form of flow equations.
The subject of fluid mechanics includes fluid statics and fluid dynamics. As demonstrated in Chapter 4, the hydrological equation relates the pressure change in a motionless fluid and serves as the foundation for a basic model of the Earth’s atmosphere.
Students in mechanical engineering or other engineering disciplines where fluid mechanics is the core subject are the primary audience for this text. Aviation (or space travel), medicine, and architecture are disciplines in which mechanics plays an important role. However, it is important to note that other fields, like biological technology, also exhibit evidence of fluid flow. The human body contains many different fluid flows, some of which are as natural as air in the respiratory tract and liquid urine in the renal system. Other fluids, such as blood in the circulatory system and synovial fluid that lubricates joints, have non-Newtonian properties, as do many synthetic fluids such as paints, coatings, and pastes. Chapters 2, 15, and 16 provide a brief introduction to the rheology and flow properties of non-Newtonian fluids.
As stated in its title, this text aims to introduce mechanics to the student. It covers topics you would normally encounter in the first and second years of a three-year mechanical engineering course or the first and second years of a four-year technical engineering course, as well as some topics covered in more detail in later years. The first ten chapters cover material suitable for a first-year fluid mechanics course or module. The remaining eight chapters discuss compressible flow, flow through axial-flow turbomachine blades, internal viscous fluid flow, laminar boundaries, and turbulent flow. There are many other books that have similar content but often consist of more than one calculation. While mathematics plays a crucial role in fluid flow analysis, it remains accessible to most students due to the focus on comprehending its fundamental physics. Physics-based physics derives the flow factors from a limited set of fundamental equivalents. By calculating large numbers between these basic parameters and the final results, one can solve technical problems without losing sight of the main purpose. Basic knowledge of components is required, but not for vector analysis. We don’t require Tensor text and analysis, and we restrict the account’s use to a minimum.
Some teachers may find certain subjects challenging to teach. We recommend using the Ipsen method, a simple calculation method, to approach dimensional analysis and eliminate consecutive dimensions. This technique, according to the author, offers pedagogical advantages over the widely used Rayleigh method, which may mislead students into believing that simple laws can represent any process. formula. The book emphasizes the importance of dimensional and quantitative analysis. The author also discovered that demonstrating to students the evolution of the linear force equation in Chapter 9 was a simpler task than employing Reynolds’ transport theorem. This method effectively illustrates the connection between the standard form F=ma of Newton’s second law of motion and obviates the need to introduce a completely new concept, thereby paving the way to the ultimate outcome. Most texts treat compressible flow differently, often developing simulations in different ways rather than the same. We limit the analysis of turbomachines to axial flow machines and heavily rely on Chapters 3, 10, and 11.
‘Why do we need a mechanics textbook that covers many equations and algebra when computer programs such as FLUENT and PHOENICS are now available that can calculate many flow states very well? The first thing we need to think about is what the term actually means in this particular context.
The definition of the function, or all elements, must be in balance. In fluid mechanics, the Navier-Stokes equation, a special nonlinear part of the equation, is extremely complex and solves practical problems using simple or approximate methods. Common assumptions are that all fluids remain constant, that temperature (an important property that characterizes everything as a fluid) plays no role, and that the flow is stable (that is, it does not change with time at any point in the fluid).
