Brief Handbook Description: This unit aims to develop an understanding of:

* 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.

* 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:

* 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.

* 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:

* 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.

* 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.
Assumed Knowledge: Fundamentals of thermodynamics are needed to begin this more advanced course.

# Activity Name Hours per Week Sessions per Week Weeks per Semester
1 Independent Study 6.00
2 Lecture 2.00 2 13
3 Tutorial 2.00 2 12
4 Laboratory 3.00 1 2
T&L Activities: Lecture: Material will be presented with an emphasis on explaining concepts and presenting worked solutions of sample problems. Lecture notes will be available on the web. Lecture notes include references to relevant sections of the textbooks.

Tutorial: Tutors will work through separate tutorial problems (not out of the homework) with the class. They will use these problems as a vehicle to reinforce the theory and problem solving techniques required for this course. Tutors will also answer questions relating to the homework assignments.

Laboratory: 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. There is no report. Instead students will analyse and discuss the results with the assistance of the demonstrator during the laboratory session.

Independent Study: Homework assignments. Understanding of these assignments will be assessed through the quizzes.

Learning outcomes are the key abilities and knowledge that will be assessed in this unit. They are listed according to the course goal supported by each. See Assessment Tab for details how each outcome is assessed.

Assessment Description: * Indicates an assessment task that must be repeated if a student misses it due to special consideration

Quiz: Four quizzes spread throughout the semester. Quizzes test understanding of the material covered in the lectures, homework assignments and tutorials.

Lab: Two laboratory sessions assessed on the basis of participation.

Final Exam: One two hour exam.

Reweighting of assessments: Quizzes missed due to circumstances for which special consideration is granted will lead to reweighting of remaining quizzes and exam only (not labs).

Lateness penalties: Not applicable. All assessments are completed during timetabled classes.

Moderation: There may be statistically defensible moderation when combining the marks from each component to ensure consistency of marking between markers, and alignment of final grades with unit outcomes.
Assessment Feedback: Quiz solutions (answers and method) be posted on the unit of study webpage immediately after the quiz.

Quizzes will be returned with feedback indicating why marks have been deducted.

A description of common errors, explaining why they are wrong and how to avoid them, will be posted by the tutor marking the quiz on the online discussion forum after the return of each assessment.
Grading:
