MECH ENG 4104 - Advanced Topics in Fluid Mechanics
North Terrace Campus - Semester 1 - 2014
General Course Information
Course Code MECH ENG 4104 Course Advanced Topics in Fluid Mechanics Coordinating Unit School of Mechanical Engineering Term Semester 1 Level Undergraduate Location/s North Terrace Campus Units 3 Contact Up to 4 hours lectures/tutorials and 3 hours laboratories per week Incompatible MECH ENG 4023, MECH ENG 4140 Assumed Knowledge MECH ENG 1007, MECH ENG 2021, MECH ENG 3101, 6 units of Level II Applied Mathematics courses Course Description This course builds on the concepts learned in core Mechanical Engineering courses and extends these to provide practical interpretive and predictive methods. The syllabus begins with a practical and theoretical overview of modern flow measurement techniques and the methods used to interpret velocity and flow data. These are then applied to the fundamental flow cases such as boundary layers and free shear flows. Specific applications of these flow cases are then given through the study of internal flow systems and external flows around air, ground and sea-going vehicles. These include wind tunnels, race cars, high-performance yachts, swimmers, sports balls, birds and fish.
Course Coordinator: Associate Professor Richard Kelso

Specific Course Requirements
The University's policy on Assessment for Coursework Programs is based on the following four principles:
- Assessment must encourage and reinforce learning.
- Assessment must enable robust and fair judgements about student performance.
- Assessment practices must be fair and equitable to students and give them the opportunity to demonstrate what they have learned.
- Assessment must maintain academic standards.
All assessment tasks are formative. There are 4 assignments, each worth approximately 3.75% of the assessment, a laboratory that is worth 5%, and a small project that is worth 10% of the total assessment. The open book exam is worth 70%. All assignments are due by 5:00pm on the due date. Details of each task are tabulated below. This schedule is subject to change during the semester. See MyUni for details.

Assessment Related RequirementsNONE
All assignments will are based on a problem-solving format. In each case a practical problem will be presented and the students will be asked to provide a solution to that problem. The problem format and difficulty are the same as the final exam. Each student’s submission will be assessed primarily on the quality of their approach to the problem. Students are required to state all assumptions used in their solutions, provide appropriate diagrams, and to follow a standard solution and presentation procedure known as the “problem solving protocol”. Approximately 10% of the marks of each problem are awarded for fulfilling these requirements.
This laboratory consists of an experimental investigation of the lift produced by a spinning cylinder mounted in a wind tunnel. Students will be required to measure the lift force, air speed and cylinder rotational speed in order to calculate the lift coefficient, and then compare the data with published values. Students are required to submit individual reports for each laboratory. Students must have submitted a report and scored at least 35% overall to be eligible to pass the course. Further details are provided by the laboratory demonstrators.
A group project will be undertaken by each student, involving a literature review, analysis and/or experiment. Projects will be assessed on the basis of a report and, depending on class numbers, a presentation to the class. Students are encouraged to form groups of 2 or three students. A list of possible project topics will be provided during the lectures.
Individual assignments are to be submitted by each student to the submissions box on Level 2, Engineering South. Unless students are otherwise notified, assignments must be submitted by 5.00pm exactly two weeks after each assignment is issued. Submitted assignments must be accompanied by an assessment cover sheet, available from the front office S116 or near the assignment submission boxes. Late assignments will be penalised 10% per day. Extensions for assignments will only be given in exceptional circumstances and a case for this with supporting documentation can be made in writing after a lecture or via email to the lecturer. Assignments will be assessed and returned within 2 weeks of the due date, along with a “model” solution prepared by the lecturer. There will be no opportunities for re-submission of work of unacceptable standard. Due to the large size of the class, feedback on assignments will be provided by limited comments on the returned assignments and general feedback given during the lectures and tutorials.
Grades for your performance in this course will be awarded in accordance with the following scheme:
M10 (Coursework Mark Scheme) Grade Mark Description FNS Fail No Submission F 1-49 Fail P 50-64 Pass C 65-74 Credit D 75-84 Distinction HD 85-100 High Distinction CN Continuing NFE No Formal Examination RP Result Pending
Further details of the grades/results can be obtained from Examinations.
Grade Descriptors are available which provide a general guide to the standard of work that is expected at each grade level. More information at Assessment for Coursework Programs.
Final results for this course will be made available through Access Adelaide.
The University places a high priority on approaches to learning and teaching that enhance the student experience. Feedback is sought from students in a variety of ways including on-going engagement with staff, the use of online discussion boards and the use of Student Experience of Learning and Teaching (SELT) surveys as well as GOS surveys and Program reviews.
SELTs are an important source of information to inform individual teaching practice, decisions about teaching duties, and course and program curriculum design. They enable the University to assess how effectively its learning environments and teaching practices facilitate student engagement and learning outcomes. Under the current SELT Policy (http://www.adelaide.edu.au/policies/101/) course SELTs are mandated and must be conducted at the conclusion of each term/semester/trimester for every course offering. Feedback on issues raised through course SELT surveys is made available to enrolled students through various resources (e.g. MyUni). In addition aggregated course SELT data is available.

Students are reminded that in order to maintain the academic integrity of all programs and courses, the university has a zero-tolerance approach to students offering money or significant value goods or services to any staff member who is involved in their teaching or assessment. Students offering lecturers or tutors or professional staff anything more than a small token of appreciation is totally unacceptable, in any circumstances. Staff members are obliged to report all such incidents to their supervisor/manager, who will refer them for action under the university's student’s disciplinary procedures.
The University of Adelaide is committed to regular reviews of the courses and programs it offers to students. The University of Adelaide therefore reserves the right to discontinue or vary programs and courses without notice. Please read the important information contained in the disclaimer.
