Download UoS Outline

Unit: MECH5265: Combustion (6 CP)
Mode: Normal-Day
On Offer: Yes
Level: Postgraduate
Faculty/School: School of Aerospace, Mechanical & Mechatronic Engineering
Unit Coordinator/s: Professor Masri, Assaad
Session options: Semester 2
Versions for this Unit:
Campus: Camperdown/Darlington
Pre-Requisites: (MECH3260 AND MECH3261) OR MECH9260 OR MECH8260.
Brief Handbook Description: This unit of study aims to teach the basic principles of combustion highlighting the role of chemical kinetics, fluid mechanics, and molecular transport in determining the structure of flames. Students will become familiar with laminar and turbulent combustion of gaseous and liquid fuels including the formation of pollutants. They will also be briefly introduced to various applications such as internal combustion engines, gas turbines, furnaces and fires.

This unit will cover equilibrium compositions, flammability limits, simple chemically reacting systems, detailed chemical kinetics, and the basic theory underlying laminar and turbulent combustion for both premixed and non-premixed cases. There will be an introduction to droplet combustion, the concept of mixture fraction for non-premixed flames, combustion in engines and gas turbines as well as the formation of pollutants. Fire ignition, growth, spread and suppression may also be covered with respect to safety in buildings including the hazards related to the formation of smoke and toxic products.
Assumed Knowledge: Students are expected to be familiar with the basic laws of thermodynamics, fluid mechanics and heat transfer.

2. An understanding of building design based on fire safety requirements.
3. An understanding of the fundamental theory of the combustion of non-premixed and premixed flames, laminar and turbulent flames, droplets and the theory of ignition.
4. An understanding of the role of detailed chemical kinetics in combustion and the ability to calculate the equilibrium compositions of reacting systems.
5. An understanding of pollutant formation in practical devices such as internal combustion engines and gas turbines.
6. Project work requires students to analyse combustors and fire safety. Involves the use of computational tools.

Assessment Methods:
# Name Group Weight Due Week Outcomes
1 Assignments and quizzes (two each) No 20.00 Multiple Weeks 1, 2, 3, 4, 5,
2 Project and seminar Yes 40.00 Week 13 1, 2, 3, 4, 5, 7, 8,
3 Final Exam No 40.00 Exam Period 2, 3, 4, 5,
Assessment Description: Assignment: The assignments and/or quizzes will help students absorb the concepts and stay up to date with the pace of lectures.

Project: The project report and the seminar will test the ability of students to interact in a group environment, apply the concepts to a realistic problem, and relay them effectively in the form of a seminar and report. Group projects and seminars are aspects of training that are beneficial for engineers since this is common practice in fire and combustion engineering.

Final Exam: The final examination will help evaluate the overall understanding of the concepts covered in this unit and the student`s ability to analyze and solve related problems.
Grade Type Description
Standards Based Assessment Final grades in this unit are awarded at levels of HD for High Distinction, DI (previously D) for Distinction, CR for Credit, PS (previously P) for Pass and FA (previously F) for Fail as defined by University of Sydney Assessment Policy. Details of the Assessment Policy are available on the Policies website at . Standards for grades in individual assessment tasks and the summative method for obtaining a final mark in the unit will be set out in a marking guide supplied by the unit coordinator.
Policies & Procedures: See the policies page of the faculty website at for information regarding university policies and local provisions and procedures within the Faculty of Engineering and Information Technologies.
