MECH3260: Thermal Engineering 2

This unit aims to develop an understanding of: 1) The principles of thermodynamics- energy, entropy and exergy balances- applied to pure substances, mixtures and combustion and the application of these principles to engineering processes, power and refrigeration systems. 2) The principles of heat transfer- conductive, convective, radiative heat transfer- in the context of a variety of physical situations and the application of these principles in order to design and size engineering equipment and analyse engineering processes. Course content includes: 1) Thermodynamics- properties of matter, energy, entropy and exergy balances for closed and steady state flow systems, mixtures, mixing and separation, psychrometry and air-conditioning and combustion- stoichiometry, first and second law analysis of reacting systems. 2) Heat Transfer- conduction, thermal circuits, general conduction equation, conduction through cylindrical bodies and fins, heat exchangers, transient conduction including analytic solutions, forced convection and natural convection, boiling and radiation- spectrum, intensity, surface radiative properties, environmental radiation, solar radiation. At the end of this unit students will be able to: 1) Thermodynamics- apply the principles of thermodynamics and heat transfer to engineering situations; have the ability to tackle and solve a range of problems involving thermodynamic cycles, devices such as compressors and turbines, mixtures, air conditioning, combustion. 2) Heat Transfer- have the ability to tackle and solve a range of heat transfer problems including heat exchangers, cooling by fluids, quenching, insulation and solar radiation.

Weekly Assignments: Submit your own handwritten solutions for the week’s tutorial and homework questions. These are due at 11:59pm each Sunday.

Four quizzes: Quiz questions will test your understanding of the material covered in the pre-recorded lectures, lecture worked examples, tutorials and homework problems. Questions will be of similar difficulty to the lecture worked examples, tutorial and homework problems.

Two Labs: Spark ignition and a gas turbine lab. All analysis is done during the lab session. Your analysis is then submitted at the end of the session. Assessment is based on your contributions to the session and the submitted work.

Final exam: Exam questions will test your understanding of the material covered in the pre-recorded lectures, lecture worked examples, tutorials and homework problems. Questions will be of similar difficulty to the lecture worked examples, tutorial and homework problems.

Procedures for students who have an approved application for special consideration

Quizzes: There are no replacement quizzes. If a student misses a quiz and is granted special consideration, the marks for the remaining quizzes and final exam (not labs and weekly assignments) will be reweighted.

Assessment criteria

The University awards common result grades, set out in the Coursework Policy 2014 (Schedule 1).

As a general guide, a high distinction indicates work of an exceptional standard, a distinction a very high standard, a credit a good standard, and a pass an acceptable standard.

Late submission

In accordance with University policy, these penalties apply when written work is submitted after 11:59pm on the due date:

  • Deduction of 5% of the maximum mark for each calendar day after the due date.
  • After ten calendar days late, a mark of zero will be awarded.

This unit has an exception to the standard University policy or supplementary information has been provided by the unit coordinator. This information is displayed below:

WEEKLY ASSIGNMENTS: These assignments are designed to help students to stay on track with the material and are only worth 1.5% each. As such, late submissions will not be accepted. LABS: Students are required to complete the analysis during the lab session and then submit their work at the end of the session. As such, late submissions will not be accepted.

Special consideration

If you experience short-term circumstances beyond your control, such as illness, injury or misadventure or if you have essential commitments which impact your preparation or performance in an assessment, you may be eligible for special consideration or special arrangements.

Academic integrity

The Current Student website provides information on academic honesty, academic dishonesty, and the resources available to all students.

The University expects students and staff to act ethically and honestly and will treat all allegations of academic dishonesty or plagiarism seriously.

We use similarity detection software to detect potential instances of plagiarism or other forms of academic dishonesty. If such matches indicate evidence of plagiarism or other forms of dishonesty, your teacher is required to report your work for further investigation.

Attendance and class requirements

Pre-recorded lectures: Material will be presented with an emphasis on giving students a sound understanding of concepts. It is essential that you study these lectures and read associated sections of the textbook before attending the live lectures.

Live lectures: These sessions will focus on presenting worked solutions of one or two example problems that illustrate application of material and analysis methods presented in the pre-recorded lectures.

Tutorials: Tutors will work through separate tutorial problems with the class. They will use these problems as a vehicle to reinforce the theory and problem solving techniques required for this course.

Laboratories: There are two engine experiments: gas turbine and spark ignition. Students are expected to familiarize themselves with the thermodynamic cycles and characteristics of these engines before the laboratory. During the laboratory there will be discussion of the engines, their details, their performance and what the objectives of the tests are. Students will analyse and discuss the results with the assistance of the demonstrator during the laboratory session.

Independent Study: Study the pre-recorded lectures and read through associated sections of the textbook. Work through the tutorial problems yourself after the tutorial. Do the week’s homework problems. Your solutions to the week’s tutorial and homework problems are to be submitted as the weekly assignment. These assignments are intended to help you stay on track.

Study commitment

Typically, there is a minimum expectation of 1.5-2 hours of student effort per week per credit point for units of study offered over a full semester. For a 6 credit point unit, this equates to roughly 120-150 hours of student effort in total.
