Rationale
This course builds upon students’ understanding of thermofluids to enable the design of efficient combustion systems. The properties of renewable fuels are different to fossil fuels, so characterisation of their behaviour in combustion systems is necessary to successfully transition from fossil fuels, by reducing pollution and the effects of greenhouse gasses.
Synopsis
This course will provide an overview of the nature of combustion, including the chemical reactions which drive the heat release from the fuel and air (the "reactants") and the fluid mechanics which enable the reactants to interact with the ignition source. Students will analyse how reactants are converted to products in the various types of combustion engines and furnaces. They will then investigate the special natures of liquid and solid fuels. Advanced content will include the application of the knowledge obtained to model or simulate real combustion systems.
Objectives
On successful completion of this course students should be able to:
- Analyse combustion chemistry and fundamental flow problems;
- Evaluate premixed and non-premixed combustion processes within the context of internal combustion engines and furnaces;
- Evaluate liquid fuels and their behaviour in combustion systems to enable the classification of the fuel;
- Evaluate the complex pathways of solid fuel combustion;
- Generate a model or simulation of real combustion systems;
- Critically evaluate the efficiency of combustion systems and the consequential socio-economic and environmental impacts.

Important assessment information
-
Attendance requirements:
There are no attendance requirements for this course. However, it is the students’ responsibility to study all material provided to them or required to be accessed by them to maximise their chance of meeting the objectives of the course and to be informed of course-related activities and administration. -
Requirements for students to complete each assessment item satisfactorily:
To satisfactorily complete an individual assessment item a student must achieve at least 50% of the marks for that item. -
Penalties for late submission of required work:
Students should refer to the Assessment Procedure (point 4.2.4) -
Requirements for student to be awarded a passing grade in the course:
To be assured of receiving a passing grade a student must achieve at least 50% of the total weighted marks available for the course. -
Method used to combine assessment results to attain final grade:
The final grades for students will be assigned on the basis of the aggregate of the weighted marks obtained for each of the summative items for the course. -
Examination information:
NO EXAM: There is no examination in this course. -
Examination period when Deferred/Supplementary examinations will be held:
Deferred and Supplementary examinations will be held in accordance with the Assessment Procedure . -
University Student Policies:
Students should read the USQ policies: Definitions, Assessment and Student Academic Misconduct to avoid actions which might contravene University policies and practices. These policies can be found at .
Assessment Notes
-
Students must familiarise themselves with the USQ Assessment Procedures (.
-
If electronic submission is specified for a course assessment, students will be notified of this on the Course Study Desk. The due date for an electronically submitted assessment is the date by which a student must electronically submit the assignment irrespective of holidays. The assignment files must be submitted by 11.55pm on the due date using USQ time (as displayed on the clock on the course home page; that is, Australian Eastern Standard Time).
-
USQ will NOT accept submission of assignments by facsimile or email unless expressly requested by the course examiner.
-
Referencing in Assignments must comply with the Harvard (AGPS) referencing system. This system should be used by students to format details of the information sources they have cited in their work. The Harvard (APGS) style to be used is defined by the USQ library’s referencing guide. These policies can be found at
Evaluation and Benchmarking
In meeting the University’s aims to establish quality learning and teaching for all programs, this course monitors and ensures quality assurance and improvements in at least two ways. This course:
1. conforms to the USQ Policy on Evaluation of Teaching, Courses and Programs to ensure ongoing monitoring and systematic improvement.
2. forms part of the Bachelor of Engineering (Honours) and is benchmarked against the
o internal USQ accreditation/reaccreditation processes which include (i) stringent standards in the independent accreditation of its academic programs, (ii) close integration between business and academic planning, and (iii) regular and rigorous review.
o professional accreditation standards of Engineers Australia
Other Requirements
-
Computer, e-mail and Internet access:
Students are required to have access to a personal computer, e-mail capabilities and Internet access to UConnect. Current details of computer requirements can be found at . -
Students can expect that questions in assessment items in this course may draw upon knowledge and skills that they can reasonably be expected to have acquired before enrolling in this course. This includes knowledge contained in pre-requisite courses and appropriate communication, information literacy, analytical, critical thinking, problem solving or numeracy skills. Students who do not possess such knowledge and skills should not expect the same grades as those students who do possess them.
