Unit description
The unit is designed to provide a comprehensive treatment of heat and mass transfer and a fundamental understanding of the different heat transfer modes (conduction, convection, and radiation) in practical engineering fields of interest. The students will learn how to apply the principles of heat transfer using numerical techniques to analyse existing thermo-fluid systems, and to develop designs which improve existing thermo-fluid systems. Knowledge from this unit together with the principles of Thermodynamics (MECH301) will help promote and develop sustainable engineering applications through their analysis and design as problems in heat and mass transfer.

- Analyse and interpret the characteristics of a heat transfer system undergoing conduction, convection and/or radiation processes with and without mass transfer.
- Apply analytical tools in calculations of heat and mass transfer for ideal and real world problems.
- Critically evaluate the experimental design and limitations of heat exchange systems.
- Develop an ability to collect and analyse experimental data from heat transfer experiments.
General Assessment Information
In order to pass this unit a student must obtain a mark of 50 or more for the unit (i.e. obtain a passing grade P/ CR/ D/ HD). There are no hurdle assessments.
The following conditions apply for all assessments:
For assignments handed in late the following penalties apply: 0-24hrs -25%, 24-48hrs -50%, greater than 48hrs -100%.
All assessments will be graded according to standards set in the marking rubrics. Students will receive a numerical grade for each assessment which will be representative of a fail (0-49%), pass (50-64%), credit (65-74%), distinction (75-84%) or high distinction (85-100%) as defined by the university standards based assessment guidelines. The definitions of these standards will be posted on the iLearn page. All marking rubrics specific to each assessment will be released on the iLearn page clearly indicating requirements to achieve a particular standard. These will be released well in advance of the assessment due date or are specified below.
Weekly Tutorial Questions (10/100)
Each tutorial will typically consist of 4 questions. Students will receive 1 tutorial question to attempt prior to their timetabled tutorial session. The tutor will provide feedback on the attempt and allocate either a fail grade for incorrect methodology and incorrect answer, a pass grade for sound methodology but incorrect answer, or up to a high distinction grade for sound methodology and correct answer. The maximum marks available for the first tutorial question is 0.5.
Students must individually attempt the second tutorial question during the tutorial (A maximum of 20mins will be allocated). This will be run as a weekly quiz. The tutor will check the answers and provide immediate feedback with a maximum of 0.5 marks following the grading standards indicated for the first tutorial question. The 3rd and 4th questions of each tutorial will not be assessed.
A maximum of 1 mark (out of 100 available for the unit) is available for each of the tutorial sessions from weeks 3-7 and 9-13.
Assignments (10/100)
Assignment 1: (5/100)
This individually marked assignment will test the student’s ability to apply and critically interpret the course material related to introductory concepts in heat transfer by conduction. The assignment will involve a combination of analytical calculations, design and report writing. A rubric will be provided with the assessment handout.
Assignment 2: (5/100)
This individually marked assignment will test the student’s ability to conceptually design an experimental system for heat convection. The student will design a system based on analytical calculations, whilst making considerations for suitable equipment, develop a series of theoretical results and suggest methods of experimental improvement. A rubric will be provided with the assessment handout.
Practical Laboratory Sessions (15/100)
Two individual lab reports written for two unique experiments. Attendance will be taken at the practical sessions.The student must be present in order to submit a lab report. The location of the practical sessions will be in F9C110. Precise details on time will be advised via the iLearn page. Both laboratory reports will be assessed according to a rubric to be made available on the iLearn page.
Laboratory Report 1: (7/100)
The first experiment will demonstrate the operation of heat exchangers. Students will test a particular heat exchanger design, acquire data, and compare to theoretical calculations of heat exchanger performance. A laboratory report is then handed in.
Laboratory Report 2: (8/100)
The second experiment will demonstrate experimental techniques used to take measurements of conduction and convection. The data collected will be presented and interpreted along with some theoretical calculations. A laboratory report is then handed in.
Mid Session & Final Examinations (65/100)
Mid-Session Test: (15/100)
An in-class 1hr test assessing material delivered between weeks 1 and 7.
Final Examination: (50/100)
A final examination (3hrs) assessing all material (weeks 1-13) delivered throughout the unit.
If you receive special consideration for the final exam, a supplementary exam will be scheduled in December 2019. By making a special consideration application for the final exam you are declaring yourself available for a resit during the supplementary examination period and will not be eligible for a second special consideration approval based on pre-existing commitments. Please ensure you are familiar with the policy prior to submitting an application. Approved applicants will receive an individual notification one week prior to the exam with the exact date and time of their supplementary examination.
