ENEM14011 - Energy Conversion

General Information

Unit Synopsis

This unit introduces you to key concepts and principles required to analyse problems involving heat exchange and energy conversion. You will analyse and design heat exchangers and analyse the performance of compressors, internal combustion engines, gas turbines and jet propulsion. You will analyse combustion processes and estimate pollutant emissions, and analyse and design nozzles to promote safe and efficient combustion. You will prepare professional documents that demonstrate critical evaluation of results. You will be required to show your ability to work productively to solve problems, and document and communicate your work clearly in a professional manner. On-campus students will be required to attend laboratory sessions to promote development of unit learning outcomes. Mixed Mode (online) students will be required to attend a residential school to attend laboratory sessions and an in-class test to promote development of unit learning outcomes.

Attendance Requirements

All on-campus students are expected to attend scheduled classes – in some units, these classes are identified as a mandatory (pass/fail) component and attendance is compulsory. International students, on a student visa, must maintain a full time study load and meet both attendance and academic progress requirements in each study period (satisfactory attendance for International students is defined as maintaining at least an 80% attendance record).

Assessment Overview

Recommended Student Time Commitment

Each 6-credit Undergraduate unit at CQUniversity requires an overall time commitment of an average of 12.5 hours of study per week, making a total of 150 hours for the unit.

Assessment Tasks

Assessment Task Weighting
1. In-class Test(s) 15%
2. Laboratory/Practical 15%
3. Online Test 15%
4. Examination 55%

This is a graded unit: your overall grade will be calculated from the marks or grades for each assessment task, based on the relative weightings shown in the table above. You must obtain an overall mark for the unit of at least 50%, or an overall grade of ‘pass’ in order to pass the unit. If any ‘pass/fail’ tasks are shown in the table above they must also be completed successfully (‘pass’ grade). You must also meet any minimum mark requirements specified for a particular assessment task, as detailed in the ‘assessment task’ section (note that in some instances, the minimum mark for a task may be greater than 50%).

Feedback, Recommendations and Responses

Every unit is reviewed for enhancement each year. At the most recent review, the following staff and student feedback items were identified and recommendations were made.

Source: Student feedback.
Feedback
The unit was well run.
Recommendation
The unit will be run in the same manner to support students' learning.
Action Taken
The unit will be run in the same manner in the future.
Source: Student feedback.
Feedback
The tutorial solutions could be improved.
Recommendation
Videos of the tutorial questions being solved are available from previous offerings of this unit. Developing a new video for each tutorial problem is currently being investigated.
Action Taken
Videos are being used by students to learn the content.
Source: Student feedback.
Feedback
Assessment of learning in labs through interviews was well received.
Recommendation
It is recommended that the practice of assessing the learning of labs through an interview is continued.
Action Taken
This practice has continued.
Source: Unit coordinator reflection
Feedback
There is misalignment between assignment performance and exam performance. Student performance in the exam is poor even though questions were similar to tutorial questions and textbook examples.
Recommendation
Adjust the assessment weightings and type to encourage higher individual achievement in an authentic manner.
Action Taken
Nil.
Source: Student feedback
Feedback
Students have commented that the use of an individual interview to assess the lab component of the unit is beneficial to their learning.
Recommendation
Continue the use of individual interviews for lab assessments.
Action Taken
Nil.
Unit learning Outcomes

On successful completion of this unit, you will be able to:

  1. Analyse and explain the principles of heat transfer and conversion between heat energy and mechanical power
  2. Analyse and evaluate the performance of heat exchangers and internal combustion engines
  3. Analyse and explain combustion calculations and processes
  4. Analyse and evaluate the performance of gas turbines with respect to jet propulsion
  5. Analyse and evaluate the performance of nozzles with respect to jet propulsion
  6. Analyse and evaluate the performance of compressors.

This unit in the Mechanical Engineering course helps students meet the Engineers Australia's stage one competencies.
