Introduction to turbomachinery

ME-342 / 2 crédits

Enseignant: Yim Eunok

Langue: Anglais

Summary

The course provides a foundational understanding of turbomachines, covering their classification, fundamental principles of fluid mechanics and key performance parameters. It delves into coordinate systems, velocity analysis, and the application of conservation laws to turbomachinery.

Content

This course provides a comprehensive introduction to fluid mechanics and turbomachinery, beginning with fundamental principles before progressing to more specialized topics.
Students will first learn the essential equations governing fluid flow, including the conservation of mass, energy, and momentum. They will explore flow characteristics in pipes, the differences between laminar and turbulent flow, and how to calculate energy losses in both straight pipes and complex piping systems. The course also covers vortex phenomena and thrust generation in certain types of turbomachinery, laying the groundwork for understanding fluid motion and its effects.
Building on these foundations, students will then be introduced to the basic principles of turbomachines. They will learn how and why turbomachines work, the differences between turbines and pumps, and the importance of minimizing energy losses. The course will also cover blade design, the selection of appropriate turbomachines for specific applications, and the fundamentals of scaling machines from prototypes to various sizes.
By the end of the course, students will have the necessary knowledge to analyze fluid flow in engineering systems and advance to more specialized work in turbomachinery design, development, and research.
