Blade Design and Analysis for Steam Turbines by Murari P. Singh, George M. Lucas

Preface: Turbine engineers and designers have made remarkable improvements in the efficiency and reliability of industrial steam turbines over the last 30 years. Remarkable improvements have been achieved for products that already had over 100 years of technical development behind them. For most of those first 100 years, the analysis of turbine blades had concentrated on the behavior of individual blades. A key change, and one of the most significant advances in turbine reliability, was the development and application of analytical techniques that make it possible to characterize and explain the behavior not simply of individual turbine blades, but of entire bladed disk assemblies. 

Advancements in modal analysis and testing, fatigue analysis, creep analysis, fracture mechanics, aerodynamic theories, and the development of many new materials and manufacturing processes cleared the path for the design of more powerful, more efficient, and more reliable turbines. It became evident that design of blades is a multidiscipline activity. For a proper reliability assessment of a design, one needs to understand many fields of science and these must be applied as need be. These advancements helped designers to extend the capabilities of designs beyond past experience. This also helped to explain past successes and failures of components. 

The simultaneous development of powerful and inexpensive computers has made it practical to quickly and efficiently carry out the calculations necessary to apply these advanced analytical techniques to the routine design of new and replacement blades and rotors for industrial steam turbines. Nowhere have these advances had a greater influence than on the design of critical service process compressor drives for the refining and petrochemical industries. Large drivers for ethylene and LNG processes exceeding 75 MW in power are in successful service. Older designs using double-flow exhausts with short, but very strong, blades have been supplanted in newer designs by single-flow exhausts with taller, but more reliable and aerodynamically sophisticated, stages. Inlet pressure and temperatures of 2000 psig/1000°F (140 barg/540°C) have become almost common in new process drive applications.

The purpose of this book is to introduce these advances in a concise volume and provide an easy-to-understand reference for practicing engineers who are involved in the design, specification, and evaluation of industrial steam turbines in general, and critical process compressor drivers in particular. This text has also attempted to present a unified view of concepts and techniques needed in the understanding of blade design. It includes some advanced concepts such as life estimation. One chapter is dedicated in introducing the reader and designers to the effect of uncertainty of input variables on the reliability of the design. Probabilistic-type analysis is introduced for reliability estimation, as it is said that every design decision has some risk associated with it and risk may be managed if it is known. 

We would like to thank each person and the many industries whose works have been referenced in the book. We also take this opportunity to apologize to those whose work might not have been referenced by mistake. Thanks to the many associates during our employment and consulting work whose thoughts guided the selection of many materials. We hope these will help readers in their work or at least make them think. Last but not the least, many thanks to Seema Singh for reading the manuscript word by word and making numerous suggestions for changes that made the work better and more readable.
