Sample subject outline - Semester 2 2013

Note: Subject outlines often change before the semester begins. Below is a sample outline.

Rationale

Many engineers have to deal with fluid flows at some stage of their careers. A substantial number will specialise in aspects of wind, water, environmental and machine systems engineering. This unit will address the fundamental principles of fluid behaviour and apply these principles to the analysis and design of pipe flow and hydraulic systems. Computational Fluid Dynamics is also introduced at a basic level to illustrate how it is used to analyse simple engineering problems. This is the foundation unit in fluids and as such is offered in the second year of study. The material covered in this unit forms a basis for subsequent fluid dynamics and biofluids units. It relies on a prior knowledge of physics, mathematics and solid mechanics.

Aims

The aim of this unit is to introduce the fundamental concepts and principles of fluid mechanics that are applied by engineers to understand and characterise these systems using simple examples of the application of the relevant principles.

Objectives

On completion of this unit you should be able to:
1. Apply and solve problems related to hydrostatics.
2. Explain how basic fluid mechanics is used in the design of hydraulic structures and fluid systems.
3. Apply the energy and momentum equations to hydraulic systems and machines.
4. Understand basic principals surrounding the use of computational fluid

Content

Topic
1. Units and Properties of Fluids
2. Pressure and Pressure Measurement
3. Hydrostatics
4. Energy and Momentum Equation
5. Losses in Pipe Systems
6. Introduction to Computational Fluid Dynamics

Approaches to Teaching and Learning

Total Hours per week: 4
Lectures: 2 hrs
Tutorials: 1 hr
Computer Laboratory: 1 hr

Teaching Mode:
ENB221 will use a combination of lectures, tutorials and a laboratory experiment with real world examples to realise the learning outcomes of the unit. The fundamental theories and principles will be introduced through lectures. Problem solving tasks of varying levels of complexity will be structured to draw out the concepts covered in the lectures. The laboratory exercise will enhance the learning experiences in this unit.

Lectures: Students will attend a 2-hour lecture every week which will present the fundamental theoretical principles that govern the behaviour of fluid and fluid systems. Each theoretical concept will be introduced to the class using appropriate real world examples in the lecture.

Tutorials: Students will attend a 1-hour tutorial every week which will be comprised of two aspects. The first aspect is the application of the theoretical principles introduced in the lectures to solve a range of numerical problems. Tutors will guide the students in formulating appropriate solution methodologies and solve problems. The second aspect will be a brief session involving a discussion of a typical application example that relates to a succeeding lecture topic which the class will have to analyse and develop possible interpretations. This will prepare the class on what to expect in the next lecture class.

Laboratory Experiment: The class will be divided in small teams which will perform a laboratory experiment relevant to a real world context. Each team will produce a report summarising and discussing their results.

Academic Honesty

QUT is committed to maintaining high academic standards to protect the value of its qualifications. To assist you in assuring the academic integrity of your assessment you are encouraged to make use of the support materials and services available to help you consider and check your assessment items. Important information about the university's approach to academic integrity of assessment is on your unit Blackboard site.

A breach of academic integrity is regarded as Student Misconduct and can lead to the imposition of penalties.

Resource materials

Type: Required
Author: Cengel, Yunus A., and Cimbala, John M.
Title: Fluid Mechanics (Fundamentals and Applications)
Publisher: McGraw Hill
Year: 2010
Edition: 2nd Edition in SI Units

QUT Blackboard web site for unit ENB221. Resource material in the form of lecture notes/PowerPoint presentations will be provided. This material is designed to supplement the learning in this unit and not replace the required text.

Risk assessment statement

You will undertake lectures and tutorials in the traditional classrooms and lecture theatres. As such, there are no extraordinary workplace health and safety issues associated with these components of the unit.

You will be required to undertake a practical session in the laboratory under the supervision of the lecturer/tutor and technical staff of the School. In any laboratory practicas you will be advised of requirements of safe and responsible behaviour and will be required to wear appropriate protective items .

Covered shoes are required for entry to laboratory classes. Other practical laboratory rules and safety protocols are outlined on the blackboard site for the unit. A short safety quiz must be taken as a requirement of the practical component of assessment.

Disclaimer - Offer of some units is subject to viability, and information in these Unit Outlines is subject to change prior to commencement of semester.
