COMPUTER AIDED ENGINEERING

.

The following learning outcomes will be assessed:
Knowledge
An understanding of the use of commercial mathematical software packages to assist
in solving engineering problems.

Skills
the ability to develop and analyse mathematical models of the behaviour
of a component or system due to external influences and so predict the performance
of that component or system.

Important Information
You are required to submit your work within the bounds of the University Infringement of
Assessment Regulations (see your Programme Guide). Plagiarism, paraphrasing and downloading
large amounts of information from external sources, will not be tolerated and will be dealt with
severely. Although you should make full use of any source material, which would normally be an
occasional sentence and/or paragraph (referenced) followed by your own critical
analysis/evaluation. You will receive no marks for work that is not your own. Your work may be
subject to checks for originality which can include use of an electronic plagiarism detection service.
Where you are asked to submit an individual piece of work, the work must be entirely your own.
The safety of your assessments is your responsibility. You must not permit another student access
to your work.

Where referencing is required, unless otherwise stated, the Harvard referencing system must be
used (see your Programme Guide).

Please ensure that you retain a duplicate of your assignment. We are required to send samples of
student work to the external examiners for moderation purposes. It will also safeguard in the
unlikely event of your work going astray.

Problem statement

You are required to develop a 2D model of model air flow over an aircraft wing (with an aerofoil-shaped cross section)

using the SolidWorks Flow Simulation software. You will investigate the
flow pattern of air over the aerofoil and also calculate the drag force at the air speed specified by
you. For validation purposes you will compare this drag force with that over a flat plate of similar
dimensions, which you will calculate using the manual calculation methods developed in EAT223.

You should either model the aerofoil within SolidWorks itself, using the method described in the
tutorial material provided, or import an aerofoil model.

Report
Your report should include the following information:

Description

Mark
(a) A description of the aerofoil model you have used, including a screenshot.

10
(b) A table summarising any boundary conditions and constraints, with an
explanation of the values selected, where appropriate.

15
(c) Plots of the velocity and pressure profiles around the aerofoil.

20
(d) A critical evaluation of the significance of the velocity and pressure profiles,
with regard to how the aerofoil.

15
(e) The SolidWorks calculation of drag force (you should provide evidence in the
form of a screenshot that you successfully implemented this).

15
(f) Manual calculation of the equivalent flat plate drag force.

15
(g)

This mark will be allocated based on the quality of your report. 10

You should also be capable of demonstrating your model using the SolidWorks software on the
terraces.
