Unit Outline

The aim of this unit is to develop a 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 KNE213 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. This is pre-requisite for the unit KNE454 core unit in mechanical engineering.

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 steady state thermal conduction, convection and radiative transfers using practical applications involving finned or extended surface areas.
2.	Evaluate the similarity between momentum and convective heat transfer through theoretical analysis.
3.	Evaluate the convective heat transfer coefficients for flows over an external surface.
4.	Design heat exchanger by applying the basic concept in solving heat exchanger problems.

Assessment Task 4: Laboratory practice and reports

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 lab 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

Due Date:

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.
