An introduction to the use of computational fluid dynamics in aerospace engineering

Normal entry requirements for a level M degree programme and in particular a basic knowledge of the principles of fluid dynamics and numerical methods.

To provide students with:

·           an introduction to the computational solution of engineering flows

·           an understanding of basic discretisation techniques and the importance of truncation error in interpreting CFD results

·           experience in specifying and solving an example aerospace application flow and interpreting the results in order to answer engineering questions

Upon successful completion of the module, you will be able to:

a)      describe the underlying equations of fluid flow and how these equations are solved by a commercial CFD package

b)      derive basic discretisations and their associated truncation error and describe how this affects the accuracy of results

c)      specify simple engineering flows

d)      use a computer package to build a suitable mesh and solve the flows

e)      interpret the output from the package to obtain answers to engineering questions

·         Introduction to CFD and to the relevant ANSYS packages

·         Conservation laws and Navier-Stokes equations

·         Methods of mesh generation

·         Boundary condition specification

·         Basic concepts of numerical methods used in CFD

·         Truncation error and discretisation order

·         Engineering interpretation of output

·         Turbulence modelling

·        Tutorials and coursework: CFD analysis of a typical aerospace engineering problem from definition to output

44 hrs combined lectures and tutorials, 80 hrs assignment work, 2 hrs examination and 24 hrs independent learning.

Total student learning time 150 hours.
