MEC3107 Thermofluids

Semester 1, 2020 Online
Short Description: Thermofluids
Units : 1
Faculty or Section : Faculty of Health, Engineering and Sciences
School or Department : School of Mechanical and Electrical Engineering
Student contribution band : Band 2
ASCED code : 030799 - Mechanical, Industrial Enginee
Grading basis : Graded


Examiner: Ahmad Sharifian-Barforoush


Pre-requisite: (MEC2106 and ENM1600) or Students must be enrolled in one of the following Programs: GCNS or GDNS or MENS
Students cannot enrol in MEC3107 if they have successfully completed, or are currently enrolled in, MEC2101 or MEC3102


Thermofluids is the study of fluids (liquids and gasses) and their interaction with the environment. Engineers take advantage of the ability to perform tasks by changing the temperature of fluids or forcing them to flow. Through an understanding of how these processes occur, engineers are able to refine current practices and devise new systems which perform more efficiently, which is beneficial to the environment and the economy. This course builds upon MEC2106 Introduction to Thermofluids by studying more complex systems and introducing more advanced analysis techniques to investigate the performance of individual components.


The analysis of thermofluids is based around forces and energy: this is how fluids interact with other fluids and solids as part of their environment. A consequence of every process is an increase in the chaos in the universe; the implications for this in engineering systems are explored. The effects of friction on subsonic fluid flow are investigated, while the nature of heat transfer transmitted by solids and fluids is explored in detail for practical situations.


On successful completion of this course students should be able to:

  1. discriminate between systems which behave realistically and those which do not, applying this knowledge to analyse real engineering systems;
  2. analyse the effects of viscosity on the behaviour of fluids in subsonic flows;
  3. analyse the heat transfer through fluids and solids under static and dynamic conditions.

Important assessment information

  1. 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.

  2. 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.

  3. Penalties for late submission of required work:
    Students should refer to the Assessment Procedure (point 4.2.4)

  4. Requirements for student to be awarded a passing grade in the course:
    Due to COVID-19 the requirements for S1 2020 are: To be assured of receiving a passing grade a student must achieve at least 50% of the total weighted marks available for the course.

    Requirements after S1 2020:
    To be assured of receiving a passing grade a student must obtain at least 50% of the total weighted marks available for the course (i.e. the Primary Hurdle), and have satisfied the Secondary Hurdle (Supervised), i.e. the end of semester examination by achieving at least 40% of the marks available for that assessment item.

    Supplementary assessment may be offered where a student has undertaken all of the required summative assessment items and has passed the Primary Hurdle but failed to satisfy the Secondary Hurdle (Supervised), or has satisfied the Secondary Hurdle (Supervised) but failed to achieve a passing Final Grade by 5% or less of the total weighted Marks.

    To be awarded a passing grade for a supplementary assessment item (if applicable), a student must achieve at least 50% of the available marks for the supplementary assessment item as per Section 4.4.2 of the Assessment Procedure.

  5. 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.

  6. Examination information:
    Due to COVID-19 the requirements for S1 2020 are: An Open Examination is one in which candidates may have access to any printed or written material and a calculator during the examination.

    Requirements after S1 2020:
    RESTRICTED: Candidates are allowed access only to specific materials during a Restricted Examination. The only materials that candidates may use in the restricted examination for this course are:
    1. writing materials (non-electronic and free from material which could give the student an unfair advantage in the examination);
    2. calculators which cannot hold textual information (Students must note the make and model of the calculator used in the examination on the front of the answer book or examination paper where applicable):
    3. Formula sheet (An A4 sheet (two sides) containing any information that they believe will be relevant for the examination). Tables, charts and graphs needed for the solution of the examination will be provided.

  7. Examination period when Deferred/Supplementary examinations will be held:
    Due to COVID-19 the requirements for S1 2020 are: The details regarding deferred/supplementary examinations will be communicated at a later date.
