Introduction
Turbomachinery is a branch of engineering that deals with the design, analysis, and operation of machines that transfer energy between a fluid and a rotor. Examples of turbomachines include turbines, compressors, pumps, fans, blowers, and jet engines. Turbomachines are widely used in various industries such as power generation, aerospace, automotive, oil and gas, and water supply.
What is turbomachinery?
A turbomachine is a device that converts kinetic energy or potential energy of a fluid into mechanical work or vice versa. The fluid can be a gas or a liquid, such as air, steam, water, or oil. The rotor is a rotating component that has blades or vanes attached to it. The blades or vanes interact with the fluid and change its pressure, velocity, or direction.
Why is fluid mechanics important for turbomachinery?
Fluid mechanics is the science that studies the behavior of fluids under various conditions. Fluid mechanics is essential for understanding how turbomachines work and how to improve their performance and efficiency. Fluid mechanics helps to answer questions such as:
How does the fluid flow through the turbomachine?
What are the forces and torques acting on the rotor?
What are the losses and inefficiencies in the system?
How can the flow be controlled or modified?
How can the noise and vibration be reduced?
Who is Wislicenus and what is his contribution to the field?
George F. Wislicenus was a German-American engineer who specialized in turbomachinery. He was born in 1899 in Berlin and immigrated to the United States in 1925. He worked as a professor at Purdue University and later as a consultant for several companies such as General Electric, Westinghouse, and Pratt & Whitney. He wrote several books and papers on turbomachinery, including Fluid Mechanics of Turbomachinery, which was first published in 1958.
Wislicenus was one of the pioneers in developing the modern theory of turbomachinery based on dimensional analysis and similarity laws. He also contributed to the advancement of axial-flow turbines and compressors, radial-flow turbines and compressors, centrifugal pumps and fans, and supersonic flow in turbomachines. He received many honors and awards for his work, such as the ASME Fluids Engineering Award and the AIAA Fluid Dynamics Award.
Main features of the book
Fluid Mechanics of Turbomachinery by Wislicenus is a comprehensive and authoritative book that covers the fundamentals and applications of fluid mechanics to turbomachinery. The book is divided into six chapters, each with a clear introduction, a detailed derivation of the equations, a discussion of the results, and a summary of the main points. The book also includes numerous examples and exercises to illustrate the concepts and test the understanding of the readers. The book also provides practical applications and case studies to show how the theory can be applied to real-world problems.
Overview of the contents
Chapter 1: Basic concepts and definitions
This chapter introduces the basic concepts and definitions used in fluid mechanics and turbomachinery, such as fluid properties, fluid statics, fluid dynamics, energy equation, momentum equation, continuity equation, velocity triangles, Euler equation, Bernoulli equation, and flow regimes.
Chapter 2: Dimensional analysis and similarity laws
This chapter explains how to use dimensional analysis and similarity laws to simplify and generalize the problems of fluid mechanics and turbomachinery. The chapter covers topics such as dimensional homogeneity, Buckingham's pi theorem, dimensionless parameters, Reynolds number, Mach number, specific speed, specific diameter, affinity laws, and performance curves.
Chapter 3: Flow in turbomachines
This chapter describes the general characteristics and principles of flow in turbomachines, such as flow classification, flow patterns, flow angles, flow coefficients, degree of reaction, stage loading, slip factor, incidence angle, deviation angle, blade loading, blade shape, blade profile loss, secondary flow loss, tip clearance loss, disk friction loss, windage loss, and efficiency.
Chapter 4: Axial-flow turbines and compressors
This chapter focuses on the design and analysis of axial-flow turbines and compressors, which are turbomachines that have the fluid flowing parallel to the axis of rotation. The chapter covers topics such as velocity diagrams, work done, pressure ratio, mass flow rate, degree of reaction, stage efficiency, stage loading coefficient, stall and surge phenomena, blade design methods, cascade tests, and performance characteristics.
Chapter 5: Radial-flow turbines and compressors
This chapter focuses on the design and analysis of radial-flow turbines and compressors, which are turbomachines that have the fluid flowing perpendicular to the axis of rotation. The chapter covers topics such as velocity diagrams, work done, pressure ratio, mass flow rate, degree of reaction, stage efficiency, stage loading coefficient, stall and surge phenomena, blade design methods, cascade tests, and performance characteristics.
Chapter 6: Centrifugal pumps and fans
This chapter focuses on the design and analysis of centrifugal pumps and fans, which are turbomachines that have the fluid flowing radially outward from the center of rotation. The chapter covers topics such as velocity diagrams, work done, head rise, flow rate, specific speed, specific diameter, impeller design methods, volute design methods, diffuser design methods, cavitation phenomenon, and performance characteristics.
