Unit Outline

The unit develop students' fundamental grasp of the concepts related to heat transfer. These phenomena are ubiquitous in mechanical engineering so a good understanding of them is essential for students to confidently progress to the higher stages of learning and in their future engineering career. This unit builds on material presented in ENG212 Thermal and Fluid Engineering covering more advanced topics in energy transfer and conversion. This provides students a broad range of industrial engineering thermal systems, with an emphasis placed on distinguishing between energy quality and quantity.

Intended Learning Outcomes

As per the Assessment and Results Policy 1.3, your results will reflect your achievement against specified learning outcomes.

On completion of this unit, you will be able to:


1.	Explain heat transfer processes in a variety of practical engineering applications.
2.	Evaluate the convective heat transfer coefficients for a range of flows over internal and external surfaces
3.	Design an optimised heat exchanger by applying contemporary engineering tools and principles

MEASURES INTENDED

LEARNING OUTCOME(S)


1	Understand the basic concept and apply it to solve the thermal questions.	LO1
2	Evaluate the thermal conduction and convection problems.	LO2

Assessment Task 2: Heat exchanger design

Task Description:

Design a practical heat changer through three lab practices that combine the knowledge in thermal conduction, thermal convection, and heat exchanger performance analysis.

MEASURES INTENDED

LEARNING OUTCOME(S)


1	Apply the fundamental knowledge related to heat transfer mechanisms and its relationship to a design.	LO1, LO2
2	Incorporate the knowledge learned from the laboratory practice into design.	LO3
3	Integrate the comprehensive integration of three heat transfer mechanism into the design.	LO1, LO2, LO3
4	Document the design procedure of the heat exchanger professionally.	LO3

Assessment Task 3: Lab demonstration/Practices

Task Description:

Laboratory / Practical:
There are three labs in total, including convection lab, transient conduction lab and heat exchanger lab. Each lab is worth of 10%. The students are required to submit individual lab report for each lab within two weeks after the lab session. The reports are marked according to their achievements in the following areas:
1. Description of the theory behind the experiment and the methodology used;
2. Understanding of the experimental facility and procedure;
3. Presentation, analysis and interpretation of the data using the relevant principles;
4. Discussion of the findings;
5. Clear and concise presentation with appropriate referencing.

These lab practices demonstrate to the students the knowledge in thermal conduction and convection. They enable students to prepare for the design project.

The labs will run in Week 5/6, 7/8 and 9/10 depending on the student numbers. All labs must be completed before week 10 so that students will be ready for the design project.

The lab reports are due within 2 weeks of the lab session.

Task Length:

Three 2-hour sessions, and written technical report of 10-15 pages

2	Explain the experimental facility and conduct the error analysis caused by the sensors’ accuracy and human/system set up.	LO3
3	Analyse and interpret the data and justify the finding using the relevant principles.	LO1, LO2, LO3

Assessment Task 4: Invigilated exam

Task Description:

A single, three-hour semi-open book exam requires students to demonstrate learning
from all teaching activities including lectures, tutorials, laboratory sessions and design project.
A four-page A4 exercise book of handwritten formula sheets is permitted to be taken into the examination, but no other written materials are allowed. Be noted that no detailed solutions of class examples and tutorial questions are allowed in the handwritten formula sheets.

Amongst the assessment for this unit is an invigilated exam, which assess ILOs 1, 2 and 3, which map to CLO 1: “Formulate substantiated conclusions for an assortment of contemporary engineering problems through applying local and advanced engineering knowledge, and established and emerging methods of engineering analysis.”, which in turn maps to the “Knowledge and Skill Base” group of competencies within the Engineers Australia Stage 1 Competency standards for Professional Engineer. The exam is required because this unit is primarily designed to provide a solid technical foundation for the methods of structural analysis to be employed in later structural design units.

The exam also aligns with the co-taught unit ENG311, and allows synergy in delivery. However, in keeping with the higher level ILOs in this postgraduate unit, the assessment of the exam is higher to allow for a high level understanding of the concept, which is one of the key differentiations between this unit and its undergraduate counterpart.

How your final result is determined

To pass this unit, you need to demonstrate your attainment of each of the Intended Learning Outcomes, achieve a final unit grade of 50% or greater, and pass any hurdle tasks.

Submission of assignments

Where practicable, assignments should be submitted to an assignment submission folder in MYLO. You must submit assignments by the due date or receive a penalty (unless an extension of time has been approved by the Unit Coordinator). Students submitting any assignment in hard copy, or because of a practicum finalisation, must attach a student cover sheet and signed declaration for the submission to be accepted for marking.

Requests for extensions

If you are unable to submit an assessment task by the due date, you should apply for an extension.

A request for an extension should first be discussed with your Unit Coordinator or teaching support team where possible. A request for an extension must be submitted by the assessment due date, except where you can provide evidence it was not possible to do so. Typically, an application for an extension will be supported by documentary evidence: however, where it is not possible for you to provide evidence please contact your Unit Coordinator.

The Unit Coordinator must notify you of the outcome of an extension request within 3 working days of receiving the request.

Late penalties

Assignments submitted after the deadline will receive a late penalty of 5% of the original available mark for each calendar day (or part day) that the assignment is late. Late submissions will not be accepted more than 10 calendar days after the due date, or after assignments have been returned to other students on a scheduled date, whichever occurs first. Further information on Late Penalties can be found on the Assessments and Results Procedure.

Review of results and appeals

You are entitled to ask for a review of the marking and grading of your assessment task if there is an irregularity in the marking standards or an error in the process for determining the outcome of an assessment. Details on how to request a review of a mark for an assignment are outlined in the Review and Appeal of Academic Decisions Procedure.
