The finite element method has undergone a major paradigm shift from a detailed mathematical background for writing tailor-made computer programs to a user-based approach for applying available software to engineering analysis and design scenarios. This textbook begins with a concise overview of fluid mechanics, motivated by numerous engineering applications and examples. It then presents and analyzes major types of fluid machinery and the major classes of turbines. The final chapters cover pump technology. The result is a text that includes background concepts and practical coverage of turbine technologies, with case studies, problems, and examples using ANSYS code to show use of a specific program.
