NUMERICAL METHODS & CFD - 2018/9
Module code: ENG3165
Third year module in numerical methods for engineering problems.
The module introduces the typical methods used in engineering practice to obtain numerical solutions to problems described by differential equations. MATLAB is used to allow the students to test the numerical methods on appropriate problems. The emphasis is on understanding the applicability and limitations of the methods used in engineering software. The students are introduced to a commercial CFD package and solve a simple engineering flow problem of interest to their discipline.

|Assessment type||Unit of assessment||Weighting|
|Coursework||NUMERICAL METHODS ASSIGNMENT||15|
The assessment strategy is designed to provide students with the opportunity to demonstrate understanding of the basic numerical methods as well as the ability to select appropriate methods and obtain numerical solutions to engineering problems. The CFD coursework assignment tests the students’ ability to obtain a solution to a flow problem using a commercial CFD solver and their awareness of the possible sources of error in the solution. The numerical methods coursework assignment tests the students’ ability to select an appropriate numerical method for an engineering problem and their ability to code this solution method in MATLAB. The final examination assesses the students' theoretical knowledge of numerical methods and CFD, as well as their ability to solve simple problems.
Thus, the summative assessment for this module consists of:
CFD assignment – [Learning outcomes 2,3] – 10 hours (15%)
Numerical methods assignment [Learning outcomes 1,2] – 10 hours (15%)
Examination [Learning outcomes 1,2] – 2 hours (70%)
Formative assessment and feedback
Formative verbal assessment is given in tutorials and lectures (through electronic voting sessions)
Written feedback is given on coursework assessments
- introduce the students to the numerical methods used for solution of engineering problems
- expand the students' programming skills in MATLAB to allow them to implement numerical methods for engineering problems
- provide the students with the criteria for the selection of appropriate methods and to critcally assess the validity of their solutions
- enable the students to understand the steps needed to compute a solution to a problem in fluid dynamics using a CFD code and to understand the possible sources of error in a CFD simulation
- enable the students to use a CFD code to run a simulation of a simple flow of engineering interest, including pre- and post-processing

Methods of Teaching / Learning
The learning and teaching strategy is designed to introduce numerical methods and CFD through theory with worked examples carried out by the students. This is delivered through lectures and tutorial classes with the students conducting two practical coursework assignments.
The learning and teaching methods include:
2 hours lectures per week (11 weeks = 22 hours)
2 hours tutorial per week (10 weeks = 20 hours)
Coursework assignments (20 hours)
Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
