Learning outcomes |
The Turbomachinery course aims to provide a detailed understanding of the fundamental principles and applications in energy generation and conversion machinery. Students will gain in-depth knowledge of the operation, performance and design of turbomachinery, including turbines, compressors and pumps. In addition, they will learn to apply these concepts in performance analysis and practical engineering scenarios, using computational tools and experimental methods.
By the end of the course, students will be able to:
- Understand the operating principles of turbines, pumps and compressors, including axial and radial turbomachinery.
- Carry out performance and efficiency analyses on a variety of turbomachines.
- Identify the mechanisms that contribute to performance degradation.
- Apply computer simulation techniques to model and analyze the behavior and develop basic turbomachinery designs,

Syllabus |
This course provides a detailed introduction to the operation, performance and design of turbomachinery, covering fundamental topics in fluid mechanics and thermodynamics. The content is organized into five main chapters:
1. Introduction to Turbomachinery: components, classification and types of turbomachinery.
2. Fluid Mechanics in Turbomachinery: Fundamental laws, Euler's equation, velocity triangle, efficiency.
3. Axial turbines: Force analysis, velocity triangle, turbine and compressor stages, losses and efficiency.
4.4Dimensnal Analysis of Turbomachines: Buckingham p theorem, Dimensional Analysis for incompressible flow, Performance Characteristics and operating curves, Specific speed and specific diameter and Cordier diagram
5.Radial turbomachinery: Thermodynamic analysis, impeller blade shape, performance curve and slip factors.
6.CFD analysis of turbomachinery: geometric design of the rotor, mesh generation and numerical simulation.

Teaching Methodologies and Assessment Criteria |
Grading is based on:
The assessment is based on:
A —a Final Project (50%)
Practical project applied to the course content, with an individual or group technical report (to be defined at the beginning of the semester)
B — Computational Practical Work / Guided Exercises (10%)
Set of exercises and/or computational tasks carried out throughout the semester, submitted in a format defined by the professor
C — a Test (40%)
Approval criteria and access to the exam:
For approval in continuous assessment:
A = 10/20, B = 10/20 and C = 10/20
For access to the exam:
Component C (Attendance Test) must have at least 7/20
In the final exam, only component C is eligible for improvement
Final grade in exam: 50% × A + 10% × B + 40% × Exam
Office hours: Mondays, 2pm-4pm.
