Summary and Aims of the course
This course will focus on the terminology, principles and methods of CFD – Computational
Fluid Dynamics.
CFD can be applied in many areas of engineering, including aerodynamics, hydrodynamics,
air-conditioning and minerals processing, and you will find relevance towards many other
courses you are currently taking.
The aims of the course are to:
Place CFD in the context of a useful design tool for industry and a vital research tool
for thermos-fluid research across many disciplines;
Familiarize students with the basic steps and terminology associated with CFD. This
includes developing students’ understanding of the conservation laws applied to fluid
motion and heat transfer and basic computational methods including explicit, implicit
methods, discretisation schemes and stability analysis;
Course Outline: MECH4620 3 Develop practical expertise in solving CFD problems with a commercial CFD code,
ANSYS CFX; and
Develop an awareness of the power and limitations of CFD.
This course builds on knowledge gained in other courses such as Fluid Mechanics,
Thermodynamics, and Numerical Methods.
Student learning outcomes
This course is designed to address the learning outcomes below and the corresponding
Engineers Australia Stage 1 Competency Standards for Professional Engineers as shown.
The full list of Stage 1 Competency Standards may be found in Appendix A.

Lectures in the course are designed to cover the terminology and core concepts and
theories in CFD. They do not simply reiterate the texts, but build on the lecture topics using
examples taken directly from industry to show how the theory is applied in practice and the
details of when, where and how it should be applied. The WEB stream version of the course
will also be available. This provides students with the opportunity to learn the lecture content
online interactively in their own time.
Lab sessions are designed to provide you with feedback and discussion on the assignments,
and to investigate problem areas in greater depth to ensure that you understand the
application and can avoid making the same mistake again.

Course Outline: MECH4620 6Assignments Tutorial-style problems The short assignments containing 2 sets of tutorial-style problems (T1 and T2) are listed in the Course Schedule. They will involve theoretical work and calculations related to the Course materials. Assignments will be available on the Moodle website. Group project The group project involves a complete CFD analysis, from the initial concept through to CAD, meshing, pre-processing, solving, and post-processing the results. The project description will be available on Moodle. In Week 2, students need to complete a Moodle questionnaire for group allocation purposes. The groups and allocated project topics will be announced in Week 3. The report to be submitted will be a technical report in the style of a journal article or industrial project report for a client familiar with CFD; a template will be provided to you which will also contain a structured marking criteria. The report will involve you writing an abstract/executive summary, and you will be required to conduct a short review of some similar CFD you are able to find in relevant journal papers. Following this, you will write a discussion of your chosen numerical method and assumptions, and then sections relating to mesh convergence, turbulence modelling, and presentation of key results – these reflect the topics which will be covered in depth in the lectures and labs and comprise the typical structure of a research report. Individual project The individual project focuses on assesseing the individual skills in CFD anaylsis, in particular the capability of using the CFD simulation data to describe the physical bahaviors involved in the flow. The subject of the CFD investigation will be the selection from of one of the three set problems provided in Moodle. The report of the individual major project should be of similar quality as the group project report, but is to be written individually. The report is due at 4pm on Friday, Week 10. Additional details may be found in the template of the Individual project on Moodle. Presentation All submissions are expected to be neat and clearly set out. Your results are the pinnacle of all your hard work and should be treated with due respect. Presenting results clearly gives the marker the best chance of understanding your method; even if the numerical results are incorrect. Submission Work submitted late without an approved extension by the course coordinator or delegated Course Outline: MECH4620 7
authority is subject to a late penalty of 20 percent (20%) of the maximum mark possible for
that assessment item, per calendar day.
The late penalty is applied per calendar day (including weekends and public holidays) that
the assessment is overdue. There is no pro-rata of the late penalty for submissions made
part way through a day.
Work submitted after the ‘deadline for absolute fail’ is not accepted and a mark of zero will
be awarded for that assessment item.
For some assessment items, a late penalty may not be appropriate. These are clearly
indicated in the course outline, and such assessments receive a mark of zero if not
completed by the specified date. Examples include:
a. Weekly online tests or laboratory work worth a small proportion of the subject mark,
or
b. Online quizzes where answers are released to students on completion, or
c. Professional assessment tasks, where the intention is to create an authentic
assessment that has an absolute submission date, or
d.
Marking
Marking guidelines for assignment submissions will be provided at the same time as
assignment details to assist with meeting assessable requirements. Submissions will be
marked according to the marking guidelines provided.
Examinations
There will be a two-hour examination at the end of the semester.
You must be available for all tests and examinations. Final examinations for each course are
held during the University examination periods: February for Summer Term, May for T1,
August for T2, and November/December for T3.
Please visit myUNSW for Provisional Examination timetable publish dates.
For further information on exams, please see the Exams webpage.
Calculators
You will need to provide your own calculator, of a make and model approved by UNSW, for
the examinations. The list of approved calculators is shown at
student.unsw.edu.au/exam-approved-calculators-and-computers
It is your responsibility to ensure that your calculator is of an approved make and model, and
to obtain an “Approved” sticker for it from the School Office or the Engineering Student
Centre prior to the examination. Calculators not bearing an “Approved” sticker will not be
allowed into the examination room.
Course Outline: MECH4620 8Special consideration and supplementary assessment

Course Outline: MECH4620 9Feedback on the course is gathered periodically using various means, including the UNSW myExperience process, informal discussion in the final class for the course, and the School’s Student/Staff meetings. Your feedback is taken seriously, and continual improvements are made to the course based, in part, on such feedback. In this course, recent improvements resulting from student feedback include the introduction of a group project to encourage collaborative learning experiences. Also, demonstrators are now required to provide more comprehensive feedback to assignment activities during lab sessions. UNSW has an ongoing commitment to fostering a culture of learning informed by academic integrity. All UNSW students have a responsibility to adhere to this principle of academic integrity. Plagiarism undermines academic integrity and is not tolerated at UNSW. Plagiarism at UNSW is defined as using the words or ideas of others and passing them off as your own. Plagiarism is a type of intellectual theft. It can take many forms, from deliberate cheating to accidentally copying from a source without acknowledgement. UNSW has produced a website with a wealth of resources to support students to understand and avoid plagiarism, visit: student.unsw.edu.au/plagiarism. The Learning Centre assists students with understanding academic integrity and how not to plagiarise. They also hold workshops and can help students one-on-one. You are also reminded that careful time management is an important part of study and one of the identified causes of plagiarism is poor time management. Students should allow sufficient time for research, drafting and the proper referencing of sources in preparing all assessment tasks. If plagiarism is found in your work when you are in first year, your lecturer will offer you assistance to improve your academic skills. They may ask you to look at some online resources, attend the Learning Centre, or sometimes resubmit your work with the problem fixed. However more serious instances in first year, such as stealing another student’s work or paying someone to do your work, may be investigated under the Student Misconduct Procedures. Repeated plagiarism (even in first year), plagiarism after first year, or serious instances, may also be investigated under the Student Misconduct Procedures. The penalties under the procedures can include a reduction in marks, failing a course or for the most serious matters (like plagiarism in an honours thesis) even suspension from the university. The Student Misconduct Procedures are available here: www.gs.unsw.edu.au/policy/documents/studentmisconductprocedures.pdf Course Outline: MECH4620 10
