Sustainable Development Goals

Learning Goals

The main objective is to develop a mature understanding of fluid flow phenomena. But also: Introduce concepts, principles, laws, observations, and models of fluids at rest and in motion. Provide basis for understanding fluid behaviour and for engineering design and control of fluid systems. Develop competence with mass, energy and momentum balances for determining resultant interactions of flows and engineered and natural systems. Learn methods for computing head losses and flows in simple pipes and channels. Developing teamwork abilities.

Contents

Introductory concepts: fluid properties, stresses, viscosity, surface tension, Newtonian and non-Newtonian fluids, flow classification. Fluid statics: hydrostatic equation, hydrostatic pressure distribution, hydrostatic force, hydrostatic moment, buoyancy and Archimedes principle, equilibrium and stability of immersed bodies. Volume control analysis, conservation of mass, momentum and energy, momentum equation, angular momentum equation. Differential forms: continuity, Navier-Stokes and energy equations. Simple analytic solutions of the Navier-Stokes equations. Pipe and ducts flow: head loss, turbulence, flow in multiple path pipe and duct systems, Moody diagram. Similitude and Modelling. The Pi Theorem of Riabouchinsky-Buckingham. Physical similarity and model testing.

Teaching Methods

Exposition of the syllabus in theory lectures, problem solving classes, and classes with laboratory experiments.

Assessment

Continuous assessment or by final exam, in accordance with the Academic Regulations of the University of Évora.
The grades are within the interval [0,20].
The assessment method consists of the following components:
• [RL] Laboratory Report (30%).
• [T1] Test 1 (35%).
• [T2] Test 2 (35%).
• [E] Final Examination (70%)
The student can choose between 1 out of 2 possible assessment methods, where the Final Grade [NF] is calculated according to the following:
i) CONTINUOUS ASSESSMENT: NF = RL*0.30 +T1*0.35 +T2*0.35
if NF> 9.5 ^ RL> 9.5 ^ T1> 8.0 ^ T2> 8.0 then student APPROVED
ii) FINAL ASSESSMENT: NF = RL*0.3 +Ex*0.70
if NF> 9.5 ^ RL> 9.5 ^ E> 9.5 then student APPROVED
