Description

Pipeline unsteady flow; pipe networks; ocean waves; coastal engineering; time and frequency domain modelling.

Fluid Mechanics in the Built Environment is an elective course on fluid mechanics in the final year of the undergraduate curriculum for civil and natural resources engineering students. This course forms one of the two terminal courses for the fluid mechanics area of study.

The course is split into two self-contained sections that reflect a general philosophy of the course. The course aims to provide undergraduate civil and natural resources engineers with an understanding of complex, unsteady (time-dependent) fluid dynamics in urban systems, with a particular focus on our urban potable water reticulation systems and coastal infrastructure. This is the first course in the curriculum where we are dealing with systems that are inherently unsteady and the (often destructive) forces that eventuates in the exchange between kinetic and potential energies within the systems.

The course will provide you with an understanding of how the steady state design methodologies taught in earlier courses fit within a broader, “real world” context—with consumers, pump operations, wind and ocean current actions imposing continual changes onto our systems and with these systems operating in an unsteady state. You will learn analytical methods that will provide you with the tools to predict and understand unsteady flow, wave theory, wave propagation and reflection as well as system resonance. This new knowledge is built upon the conservation laws of mass, energy and momentum and you will be provided with the skills to predict as well as ultilise unsteady flows in a range of practical applications.

Learning Outcomes

  • At the conclusion of this course, it is expected that;

  • You have an appreciation of the relationship between steady state design and the inherently unsteady fluid systems in the built environment
  • You understand the potentially destructive forces that can result during the interplay between kinetic and potential energies in unsteady state flows
  • You can model (and hence predict) the impact of unsteady flows on associated pipeline and coastal infrastructures. You can extend these concepts to the development of infrastructural protection strategies
  • You can qualitatively describe fluid flow phenomena in such a way that explains fundamental unsteady flow concepts such as wave speed, group/phase velocity, air/water interactions, reflection/transmission and resonance
  • You can apply the conservation laws (mass, momentum and energy) to model unsteady fluid flows, making effective use of control volumes and the integral forms of these laws
  • You can apply the concept of inviscid irrotational flow in fluid mechanics modelling
  • You can analyse ocean wave dynamics and the impact of ocean waves on the coastline.

Timetable Note

This is a lecture and tutorial-based course scheduled for the first semester. The course will be taught in two different formats. The first part of the course (weeks 1-6) will be taught using a flipped classroom format, where detailed recorded lectures of the material you are learning each week are provided on Learn and students are expected to review these in preparation for each week according to the schedule provided on LEARN for the corresponding sections. The second part of the course will be taught in the traditional lecture format where the course material will be delivered during the lecture.

Flipped Classes (Weeks 1 – 6)
In the first half of the course, the lecture slots will be used as interactive sessions where you will attempt problems with the assistance of the lecturer to cement your understanding of the core topics. Note that you are expected to have watched all the recorded lectures for the week prior to these sessions so you are ready to ask questions. These interactive session will contain sections of “formal” lectures as dictated by your understanding of the topics and at your request. You should see these sessions as your opportunity to really understand the topic and to customise the learning experience to suit your personal needs.

The interactive sessions will be in lecture rooms early in term 1 and then shift to the computing laboratory once you have attained the skills needed to model the phenomenon. For tutorials 1-8 you will need to submit your tutorial solutions for marking at the end of each session. There are no required submissions for the later tutorials, but the content of the tutorials will form submission components of the Unsteady pipe flow modelling project.

The project will be released in week 4 and due on week 6. This is a group project and the maximum size of each group is 3 students. You are suggested to try to solve some of the project questions from week 4.

Assessment

Assessment Due Date Percentage  Description
Coastal engineering design project 10%
Coastal engineering research project 10%
Unsteady pipe flow modelling project 15%
Mid term test 30%
Tutorial submissions 5%
Final Exam 30% Final Exam


The assessment for this paper will comprise of different components – there are marks assigned for the submission of the early tutorials (weeks 1-3), three design projects, the midterm test and the final exam. The projects aim to provide you with the opportunity to work through substantial practical problems, putting into practice the analysis and design skills you have learnt. The midterm test and the final exam will focus more on the theoretical aspects of the course. The split between these different components and the number of hours you should be spending on each is given on the following table. No hours are assigned to preparation for the tests and exams as they will be part of the independent study hours shown in section 5.

Your solutions must be legible and well presented. Poorly presented material will be given 0 marks. If you suspect there is an error in the test or exam, you must make a reasonable assumption and proceed with the question. If there was indeed an error, you will not be penalised.
Applications for aegrotats or special consideration based on errors in the test/exam questions will not be accepted as the entire cohort is equally affected and any changes must be applied universally—creating no changes in your ranking and hence grade in the course.

Notes:
1. You cannot pass this course unless you achieve an average mark of at least 40% in the test and final exam.

2. All assignments must be submitted by the due date. Late submissions will not be accepted. If you are unable to complete and submit an assignment by the deadline due to personal circumstances beyond your control you should discuss this with the lecturer involved as soon as possible. Extensions in cases where it will lead to equity issues for the cohort will not be granted.

3. It is important to remember that copying another person’s work and submitting that work as your own is plagiarism. This practice is unethical and may result in disciplinary action being taken against you. For assignments that are done in groups, it is important that all students in the group play an equal role in completing the assessment.

4. Students repeating the course must undertake all parts of the course.

5. All students are expected to read the department handbook and adhere to the ethical and professional requirements of the department. In particular you must only submit work that are solely your own. https://www.canterbury.ac.nz/media/documents/oexp-engineering/civil-engineering/ CNRE-UG-Handbook---2020-final.pdf

6. In the case of an emergency that affects the whole course, the Course Coordinator, in consultation with the Dean, may change the nature, weighting and timing of assessments, e.g. tests and examination may be replaced with assignments of the same weight or different weight at a different time and/or date (which, under certain circumstances, may be outside the prescribed course dates). The ‘Special consideration’ process will also be used for unforeseen circumstances that adversely affect the academic performance of students individually. The usual grounds for this are described in the UC policy ‘Special Consideration Procedures and Guidelines’, and personal circumstances due to a wider emergency event may also qualify

Assessment and grading system

Special Considerations

Any student who has been impaired by significant exceptional and/or unforeseeable circumstances that have prevented them from completing any major assessment items, or that have impaired their performance such that the results are not representative of their true level of mastery of the course material, may apply for special consideration through the formal university process. The applicability and academic remedy/action associated with the special consideration process is listed for each assessment item below. Please refer to the University Special Consideration Regulations and Special Consideration Policies and Procedures documents for more information on the acceptable grounds for special consideration and the application process. Special Consideration for Tutorial and Projects An extension will be granted for evidence-supported requests. Extensions will typically be for up to one week, but the duration will be considered on a case-by-case basis. Students seeking an extension must contact the course coordinator as soon as possible with evidence of their situation, and preferably before the due date. Special Consideration for Midterm Tests Students will be offered an equivalent alternative test that will replace their original test mark. Special Consideration for Final Exam Students will be offered an equivalent alternative exam that will replace their original exam mark.

Special Consideration for Midterm Tests Students will be offered an equivalent alternative test that will replace their original test mark. Special Consideration for Final Exam Students will be offered an equivalent alternative exam that will replace their original exam mark.

Note on equivalent alternative assessments: Alternative assessments are only available to students who have approved special consideration applications for the assessments at an appropriate severity level. The mark on the alternative assessments will replace the original mark in the course grade calculation unless the student declines the offer or otherwise does not sit the alternative assessment, in which case the original mark will be used. This means that your mark could decrease as a result of the alternative assessment. The alternative assessment for the exam will be held on-campus in the week of 8 July 2024. It is your responsibility to ensure that you are available for these dates if you want to benefit from the academic remedy for your special consideration. All communication associated with the arrangements of these alternative assessments will be conducted using official UC email accounts. The offer to sit an alternative assessment will come with a date and time during the resit week. Students will have a clearly specified amount of time to respond to the offer. Failure to respond will be interpreted as a declined offer. If a student has applied for special consideration but the application has not been approved when arrangements are being made for the alternative assessment, they may be permitted to sit the alternative assessment, but the mark will only be applied if the application is approved by the special considerations committee at an appropriate severity level.
