Learning outcomes |
The overall objective of this course is to complement the body of knowledge and basic skills in the field of Fluid Mechanics. In this case, the focus is on very specific applications found in systems and processes involving fluids. The learning outcomes focus on the following set of skills and competencies: 1. Understand compressible flow in steady and unsteady states; 2. Understand the different types of turbomachinery; 3. Be able to describe, using fundamental equations, the operation of axial and centrifugal machines, action and reaction; 4. Establishing the conditions for water hammer; 5. Being able to insert turbomachinery into fluid networks. 6. Being able to use CFD programs to model flow in turbomachinery.

Syllabus |
The syllabus includes the following topics:
1. Introduction.
2. External flows: Resultant force on a body immersed in a flow, friction and pressure components, and aerodynamic coefficients
3. One-dimensional compressible flow: The speed of sound - Mach number. Ideal gases. Steady, isentropic, and adiabatic flow, and isentropic flow with section changes.
4. Fluid transport lines: pressure loss in the line; pipe networks (Hardy method). PumpSIM software. Incorporation of pumps and fans and prime movers.
5. Flow in turbomachinery; energy exchanges and efficiencies.
6. Dimensional analysis, characteristic curves, specific speed, and machine geometry;
7. Influence of the Reynolds number; cavitation; Euler and Bernoulli equations in a rotor;
8. Flow in radial and axial turbomachines;

Teaching Methodologies and Assessment Criteria |
The teaching method combines theoretical exposition with practical case studies, covering the framework of the topics, concepts and theory, simplifying hypotheses, and techniques inherent to each of the subjects to be taught.
Class attendance aims to facilitate the understanding of concepts, techniques, and methods of analysis, and the interpretation of methods associated with the main approaches to fluid mechanics in an industrial context.
Support materials for teaching classes and solving exercises by students will be made available in the course area on the Moodle platform.
The assessment criteria consist of practical work to be discussed in a brief report, the study of a piping installation with a pumping system, a knowledge assessment test, and a mini-project for industrial application.
