Course: 2022/2023

Fluid installations and hydraulic machinery

(15740)

Requirements (Subjects that are assumed to be known)

- All the courses in mathematics (calculus, algebra, etc.)
- Engineering fluid mechanics

The goal of this course is make the student familiar with the application of Fluid Mechanics to industry-related problems, chiefly the transport and distribution of fluids.
At the end of the course, the student must be able to:
- Understand the physical problems associated to the transport and distribution of fluids through networks.
- Make the necessary hypotheses to apply, in a rigorous way, the fluid mechanics conservation laws to real problems.
- Identify the role of the different elements existing in a transport network.
- Define the necessary steps to design and analyze a fluid transport installation.

Skills and learning outcomes

Description of contents: programme

This is an eminently practical course, so the student must master the necessary fundamental knowledges at the time on enrollment.

1.1 Primary head losses. Colebrook correlation and Moody¿s chart.
1.2 Non-circular cross-section ducts. Hydraulic diameter.
1.3 Localized head losses: Valves, Elbows, curves, expansions, contractions, etc. 1.4 Coupling of turbomachinery to hydraulic facilities.
CHAPTER 2: Steady flow of liquids in pipe networks.
2.1 Pipes in series and in parallel.
2.2 Analysis of branched ducts: the three-reservoirs problem.
2.3 Analysis of closed-loop pipe networks. Matrix algorithm and its numerical implementation.
CHAPTER 3: Unsteady phenomena in pipe flow.
3.1 Theory of unsteady incompressible flow in ducts.
3.2 Characteristic acceleration and discharge times. Quasi-steady flow.
3.3 Order-of-magnitude analysis of characteristic variables in unsteady pipenetworks flow. Non-dimensionalization of the equations.

Learning activities and methodology

The methodology will include:
(1) Lectures, where the basic knowledges will be exposed.
(2) Resolution of problems.
(3) Resolution of problems by the student, that will be useful to self-assess his/her knowledge and develop the necessary skills.
(4) The students will attend to the lab sessions and elaborate the lab reports.
