Requirements (Subjects that are assumed to be known)
- All previous courses on Mathematics (Calculus, Algebra, etc.) - Engineering Fluid Mechanics
Objectives
The objective of this course is to get the student to be able to apply Fluid Mechanics to Industrial problems; essentially to deal with networks to transport and distribute fluids. The student will learn specific techniques and will develop his capcity to deal with this kind of problems. At the end of this course, the student will be capable of: - Understand the problematics of fluid transport through networks. - Use adequate hypothesis to apply the conservation equations to real problems. - Identify the different elements in a fluid transport network. - Define the necessary steps to design and analyze a fluid distribution 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. CHAPTER 1: Steady flow of liquids in ducts 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. 3.4 Applications. Surge tanks. 3.5 Compressibility effects. Basic theory of water hammer. Reflection and transmission of waves. Applications. CHAPTER 4: Introduction to turbomachinery. 4.1 Definitions. Classification of incompressible fluid machines. 4.2 Characteristic curves of pumps ad turbines. 4.3 Cavitation in turbomachinery. 4.4 Similarity in pumps. 4.5 Similarity in turbines. 4.6 Coupling of pumps and turbines to a hydraulic network.
Learning activities and methodology
The methodology will combine lecture classes for presentation of the fundamentals with problem solving sessions. The laboratory sessions, to take place in a virtual computer room, will consist of an introduction on matlab to enable the students to use advanced mathematical techniques to solve the hydraulics equations for distribution networks. The students will have to elaborate a project and present a report.
