DESCRIPTION - summary of the module content

The governing equations of fluid mechanics, the Navier-Stokes equations (NSE), are complex and non-linear, and thus cannot be solved analytically for anything but the simplest possible cases. To solve more complex problems of real engineering interest, we typically use computational methods, solving the NSE, or equations derived from these, numerically using high performance computers. This is known as Computational Fluid Dynamics, or CFD, and is now a key tool in the development and design of almost any product which involves fluids, including but not limited to; cars, aircraft, ships, engines and power plants, renewable energy devices such as wind or tidal turbines, and many others beside. CFD can be extended to incorporate other physical processes; multiphase flow, chemical reactions and combustion, interaction with deforming or rigid structures; and can thus be applied to analyse problems in a range of industries in areas such as chemical engineering and biomedical problems.

Practical work and theory go hand in hand on this 100% coursework module, building on your experience of CFD gained in last year's Computational Engineering module (ECM3152). You will learn about the mathematical modelling of turbulence and other physical effects in CFD, numerical and coding aspects of the numerical solution of these equations, and the practical application of CFD to real-world Engineering problems, particularly through the module-length miniproject (topics developed through discussion with the module leader) and external guest speakers. The module includes an introduction to the use of the open source CFD code OpenFOAM, and also uses the commercial package ANSYS Workbench and the commercial mesher Pointwise.

Prerequisite module: ECM3152 or equivalent
 

AIMS - intentions of the module

The aim of the module is to extend your practical understanding of CFD and to complement this with a comprehension of numerical and modelling issues. You will study the theoretical aspects of numerical simulation through directed study and interaction in tutorials, and will continue to develop your modelling skills through project work, on topics decided in discussion with the lecturers.

This module covers Specific Learning Outcomes in Engineering, which apply to accredited programmes at Bachelors/MEng/Masters level. These contribute to the educational requirements for CEng registration (as defined under the UK Standard for Professional Engineering Competence – UK-SPEC).

This module correlates to references D1, P4, MU1 - MU3, ME1 - ME3 and GM2. These references are indices of the specific learning outcomes expected of Bachelors/MEng/Masters candidates set out in UK-SPEC, codified with reference to systems used by professional accrediting institutions. A full list of the standards can be found on the Engineering Council's website, at http://www.engc.org.uk
 

INTENDED LEARNING OUTCOMES (ILOs) (see assessment section below for how ILOs will be assessed)

On successful completion of this module, you should be able to:

Module Specific Skills and Knowledge:

1 apply CFD to solve problems using pre-existing packages;

2 explain and analyse the theoretical basis for CFD, both the numerical methodologies and the mathematical models used for a range of different physical problems;

3 formulate technqiues for modelling complex engineering systems using a variety of numerical techniques;

4 describe the use of CFD techniques in a variety of professional engineering contexts.

Discipline Specific Skills and Knowledge:

5 autonomously analyse and solve engineering problems.

Personal and Key Transferable/ Employment Skills and  Knowledge:

6 independently direct your learning and work towards a defined goal;

7 present your work professionally in a variety of forums, including in a classical seminar setting;

8 process and utilise information from a range of sources, including academic journals and technical publications.

SYLLABUS PLAN - summary of the structure and academic content of the module

The module content is intended to be somewhat flexible to reflect changes from year to year in current research activity, particularly through a programme of guest speakers, but would contain the following:

- numerics for CFD: FV method, differencing schemes, solution algorithms, matrix inversion;

- turbulence modelling: RANS, Reynolds Stress and LES methods;

- combustion: premixed, non-premixed combustion, combustion regimes;

- multiphase flow: dispersed and free-surface flows; simulation techniques including Lagrangian particle tracking, Eulerian two phase models and Volume of Fluid

- meshing using various tools including snappyHexMesh and Pointwise, mesh motion; applications in mixer vessels, IC engines

RE-ASSESSMENT NOTES

If a module is normally assessed entirely by coursework, all referred/deferred assessments will normally be by assignment.

If a module is normally assessed by examination or examination plus coursework, referred and deferred assessment will normally be by examination. For referrals, only the examination will count, a mark of 50% being awarded if the examination is passed. For deferrals, candidates will be awarded the higher of the deferred examination mark or the deferred examination mark combined with the original coursework mark.
