Gas Turbine Diagnostics (eBook, PDF)

Signal Processing and Fault Isolation

• Format: PDF

Produktbeschreibung

Examining methods in data filtering, trend shift detection, and fault isolation, this book provides a variety of new research tools for use in the condition monitoring of jet engines. Each method is demonstrated through numerical simulations that can be easily done using worksheets such as Excel or through MATLAB. The signal processing algorithms presented will be useful to engineers, scientists, and researchers working on fault diagnosis of gas turbine engines. The algorithms can also be used for condition and health monitoring problems in general.

Rezensionen

"Very well written and easy to understand for practical use by engineers in industry and researchers from academia and industry. ... Excellent book on the topic with comprehensive description of the theory and a simple approach for gas turbine engine performance diagnostics."

-Ashwani K. Gupta, University of Maryland, College Park, USA

"... unique ... a single reference for numerous techniques of fault analysis and isolation. The book in its 12 chapters provides an organized way for fault analysis in gas turbines. Simple algorithms using MATLAB^® are developed based on Kalman filters, neural networks and fuzzy logic, and a hybrid soft computing approach. The book is useful for both engineers and scientists interested in gas turbine diagnostics."

-Dr. Ahmed F. El-Sayed, Zagazig University, Egypt

"The book provides a good overview of the subject of signal processing and fault isolation. The book is well structured, with individual chapters providing a good overview of a specific aspect of the subject. The book would make a good reference text for a more experienced engineer, and also assist those new to the subject to learn about specific signal processing and fault isolation techniques."
-Anthony Geoffrey Sheard, Flakt Woods Limited, UK

"Today's gas turbine industry is a multi-billion dollar business. ... The use of advanced simulation and analysis has been gaining importance, particularly in the area of gas path diagnostics. Whilst academia has made important contributions, it is industry that has to employ these advanced techniques. Professor Ranjan Ganguli's book, Gas Turbine Diagnostics: Signal Processing and Fault Isolation, is an important contribution because of the blend of scholarship and industry practice."
-Professor Riti Singh, Cranfield University, UK
