Objectives

Study of the fundamentals of fluid flows. Application to pipe flow and flow over immersed bodies.

Program

1-Introduction and basic considerations
Some characteristics of fluids. Analysis of fluid behavior. Viscosity.

2-Fluid statics
Pressure at a point. Basic equation for pressure field. Manometry. Hydrostatic on a plane surface and on a curved surface.

3- Fluid Kinematics
Velocity field- Eurelian and Lagrangian descriptions. Steady and unsteady flows. Streamlines, streaklines and pathlines.
Accelaration field- material derivative. Streamline coordinates

4-The Bernoulli Equation
The Bernoulli equation along a streamline. Physical interpretation. Free jets, confined flows and flowrate measurements

5- Finite Control Volume Analysis
The Reynolds Transport Theorem. Conservation of mass- the continuity equation. Energy equation. Linear momentum equation. Examples of application.

6- Similitude, Dimensional Analysis, and Modeling.
Dimensional Analysis. Buckingham Pi Theorem. Common dimensionless groups in fluid mechanics. Modeling and similitude. Application to flow through closed conduits and flow around immersed bodies.

7- Viscous Flow in Pipes
Laminar and Turbulent flows. Poiseuille equation. Laminar flow between concentric tubes and along a wetted column. Fully turbulent flow, description and velocity profile.

8- Pipe Flow
The Moody chart. Minor losses and noncircular conduits. Single pipes and multiple pipe systems. Pipe flowrate measurements.

9- Flow Over Immersed Bodies
Boundary layer over a flat plate. Drag and lift forces. Terminal velocity of a sphere.

Mandatory literature

Munson, Bruce R.; Fundamentals of fluid mechanics. ISBN: 0-471-44250-X

Teaching methods and learning activities

In the classes the fundamental concepts are exposed .Illustrative applications of these concepts are solved. In the tutorial classes the students must have an active participation.

Evaluation Type

Distributed evaluation with final exam

Assessment Components

Description Type Time (hours) Weight (%) End date
Attendance (estimated) Participação presencial 52,00
Total: - 0,00

Eligibility for exams

Five to eight short tests, around 15 minutes each, will be given in the classes along the course. These tests will be announced in each previous theoretical class. After each chapter the students must do an exercise proposed. To have frequency, the students must do, at least, three short tests and all homework.

Calculation formula of final grade

70% for the mark in the final examination. 20% for the marks in the short tests (4 in a total of 5 will be taken on account). 10% for the homework (the number of homework done and the mark in one of this homework will be taken into consideration).

Special assessment (TE, DA, ...)

Examinations, accordingly to the calendar draw by MIEQ
