Book Description

Excerpt from Steam Turbines This book was prepared because the author experienced difficulty in finding a published text on Steam Turbines which was satisfactory for a short but thorough course for juniors or seniors in engineering colleges, following and applying the study of thermodynamics. Of many excellent books on the subject, the majority treat it too exhaustively for such class room use. The subject of thermodynamics is so widely taught today that it was not thought necessary to include even a brief review. A working knowledge of the ordinary steam cycles, the ability to use steam tables and charts, and familiarity with the ordinary laws of mechanics, are assumed. The opening chapter is intended to acquaint the reader with the general form and principal characteristics of a variety of turbines, and with the meanings of the various terms to be used. Thereafter attention is centered on the application of thermodynamic principles I to the calculation of the flow of steam through the nozzles and blade passages of the turbine, the changes in its heat, pressure and volume, and the various factors affecting efficiency. Many topics of interest and importance in turbine design have had to be omitted for the sake of brevity. Owing to the changes probable in steam table values on the completion of the work of the A. S. M. E. Committee on Steam Research and Extension of the Steam Tables, no tables or charts have been included, as is usual with turbine texts. Comments on the various facilities now available are made in Chapter II. Illustrative problems have been given at the end of the text, classified under chapter headings. It has been the author's experience that classes progress most rapidly if problems are assigned sparingly during the early part of the text, extensive use being made of the design problems when Chapter VII is reached.
