Introduction




Macchine is a textbook written by Renato Della Volpe, a professor of mechanical engineering at the University of Naples Federico II. The book is aimed primarily at students of the Bachelor's Degree in Mechanical Engineering, but it can also be useful for other engineering disciplines that deal with fluid machines.


Fluid machines are devices that convert energy between a fluid (liquid or gas) and a mechanical system. They are widely used in various fields, such as power generation, transportation, industry, agriculture, etc. Therefore, it is important for engineering students to have a good understanding of how they work, how they are designed, and how they can be optimized.


Macchine offers a comprehensive introduction to fluid machines, developing the concepts and principles in a scientifically rigorous way, while limiting the analytical aspects to the essential ones. The book covers practically all the topics in this field, from the fundamentals of fluid mechanics and thermodynamics, to the different types of turbomachines, gas turbines, combined cycles, and positive displacement machines. The book also reflects the latest technological developments in this field, especially regarding gas turbines and combined cycles, which are today very relevant and innovative applications.


Main topics covered in the book




Fundamentals of fluid mechanics and thermodynamics




The first part of the book deals with the fundamentals of fluid mechanics and thermodynamics, which are essential for understanding fluid machines. The book introduces the concepts and principles that govern the behavior of fluids (liquids and gases) in motion or at rest, such as pressure, density, viscosity, temperature, entropy, etc. The book also presents the basic equations and laws that describe the conservation of mass, momentum, energy, and entropy in fluid systems.


In addition, the book explains how to use dimensional analysis and similarity to study fluid machines. Dimensional analysis is a technique that allows us to reduce the number of variables involved in a physical problem by using dimensionless quantities. Similarity is a concept that allows us to compare different fluid systems that have similar geometric shapes or flow patterns.


Turbomachines




The second part of the book focuses on turbomachines, which are fluid machines that use rotating blades or impellers to transfer energy between a fluid and a mechanical system. Turbomachines can be classified into two main categories: turbines (which extract energy from a fluid) and compressors (which add energy to a fluid).


The book explains how to characterize turbomachines based on their geometry (axial or radial), their flow direction (inward or outward), their specific speed (low or high), etc. The book also describes how to measure the performance parameters of turbomachines, such as power output or input, efficiency, pressure ratio, etc.


Moreover, the book provides examples of different types of turbomachines that are commonly used in various applications Continuing the article. Some examples of axial turbomachines are axial fans, axial compressors, and axial turbines. These machines have blades that are aligned with the axis of rotation, and the fluid flows parallel to the axis. Axial turbomachines are suitable for high flow rates and low pressure ratios.


Some examples of radial turbomachines are centrifugal fans, centrifugal pumps, and centrifugal compressors. These machines have blades that are perpendicular to the axis of rotation, and the fluid flows radially from the center to the periphery or vice versa. Radial turbomachines are suitable for low flow rates and high pressure ratios.


Gas turbines and combined cycles




The third part of the book deals with gas turbines and combined cycles, which are applications of turbomachines that are of great interest and importance in today's world. Gas turbines are devices that use a continuous cycle of air compression, fuel combustion, and gas expansion to produce mechanical power or thrust. Combined cycles are systems that use gas turbines and steam turbines together to achieve higher efficiency and lower emissions.


The book explains the principles and components of gas turbines, such as compressors, combustors, turbines, and nozzles. The book also shows how to perform thermodynamic analysis of gas turbine cycles, such as Brayton cycle, Joule cycle, etc., and how to calculate the efficiency, power output, specific fuel consumption, etc.


Moreover, the book describes the applications and advantages of combined cycles, such as cogeneration, regeneration, intercooling, reheating, etc. The book also presents examples of different types of combined cycles that are used in power generation and propulsion, such as combined cycle power plants (CCPP), combined cycle gas turbine (CCGT), intercooled recuperated aero engine (IRA), etc.


Positive displacement machines




The fourth part of the book covers positive displacement machines, which are fluid machines that use a periodic change of volume to transfer energy between a fluid and a mechanical system. Positive displacement machines can be classified into two main categories: reciprocating (or piston) machines and rotary machines.


The book defines and compares the types of positive displacement machines based on their working principles and design aspects. The book also explains how to measure the performance parameters of positive displacement machines, such as flow rate, pressure rise, volumetric efficiency, mechanical efficiency, etc.


Furthermore, the book provides examples of different types of positive displacement machines that are used in various applications Continuing the article. Some examples of reciprocating machines are piston pumps, plunger pumps, and diaphragm pumps. These machines have a piston or a diaphragm that moves back and forth in a cylinder or a chamber, creating a periodic change of volume and pressure. Reciprocating machines are suitable for high pressure and low flow applications.


Some examples of rotary machines are gear pumps, screw pumps, and vane pumps. These machines have one or more rotating elements that create a periodic change of volume and pressure by trapping and displacing the fluid. Rotary machines are suitable for low pressure and high flow applications.


Features and benefits of the book




Scientific rigor and clarity




One of the main features and benefits of Macchine is that it develops the concepts and principles of fluid machines in a scientifically rigorous way, without compromising on clarity and simplicity.
