Sample subject outline - Semester 1 2013

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

Rationale

Many professional engineers, particularly mechanical engineers, are employed in areas involving the design, operation or maintenance of machinery and equipment which involve processes where the transfer of heat is important. To undertake analysis or design involving these heat transfer processes, you need to build on your understanding of both thermodynamics and fluid mechanics. This unit is located in the fourth year of the course, after you have completed the more fundamental units in thermodynamics and fluid mechanics.

Aims

The aim of this unit is to extend your knowledge of thermodynamics and fluid mechanics to include both the theory and practical application of the transfer of heat. It will provide you with a descriptive (qualitative) analysis of how heat is transferred, together with a quantitative ability to calculate the rate at which heat is transferred, for a range of applications where heat may be transferred by a combination of conduction, convection and radiation.

Objectives

1. Describe mechanisms of energy transfer using heat transfer theory
2. Apply principles of heat transfer theory to solve applied problems

Content

• Heat transfer mechanisms: conduction, convection and radiation.


• Thermal properties of materials


• Conduction theory: distribution of temperature, boundary conditions. Simplifications for practical applications of conduction theory.


• Convection theory: the transport of heat in a fluid. Theoretical approximations and empirical estimations for heat convection.


• Radiation heat transfer: properties of thermal radiation, solar radiation, black body radiation. Radiation exchange between surfaces.


• Heat exchangers: performance analysis and size selection.

Approaches to Teaching and Learning

Teaching Mode:
Hours per week:4
Lecture: 2 hours
Tutorial: 1 hour
Practical: 1 hour

The teaching in this unit is based around integrating theory with practice via a series of lectures, tutorials and laboratory sessions. Learning approaches include problem based and experiential (practice based) learning based on real applications. The weekly lecture sessions will present main theoretical concepts many of which will be explained using the development and solution of engineering problems. Reference will also be made to relevant sections of the text.

The weekly tutorial sessions will give you the opportunity to apply the theoretical concepts covered in the lecture to the solution of engineering problems which are designed to further develop independent learning and problem solving skills. However, the tutorial teaching staff will also provide group and independent guidance during these sessions.

You will also undertake a series of laboratory exercises which have been developed to demonstrate the application of the theoretical concepts to real engineering applications. You will be given the opportunity to further develop your experimental observation, recording and reporting skills during these sessions.

Assessment

Assessment will include lab/practical work and a final exam.You will receive ongoing oral feedback throughout the unit in tutorials and lab sessions. You'll get written feedback on the lab reports and feedback on request on the final exam.

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

Resource materials in the form of lecture notes, tutorial solutions and laboratory notes are provided on the QUT Blackboard web site. This material is designed to supplement rather replace the material presented during the lecture and tutorial sessions.

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 practical sessions in the laboratory under the supervision of the lecturer and technical staff of the School. In any laboratory practicals you will be advised of requirements of safe and responsible behaviour and will be required to wear appropriate protective items (e.g. closed shoes or steel capped shoes).

You will undergo a health and safety induction before the commencement of the practical sessions and will be issued with a safety induction card. If you do not have a safety induction card you will be denied access to laboratories.

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