Aims
The module aims to explore the underlying theory of commercial computational fluid dynamics (CFD)
codes and to investigate their performance and reliability in engineering applications.
Whilst the theoretical aspects of the method will be covered in lectures the module is intended to be practical in nature with students having the opportunity to practice via a range of tutorials and assignments using industry standard software.
Learning Outcomes
1.
Set up and validate efficient and accurate CFD models of a range of simple engineering flows under steady and unsteady conditions.
2.
Set up and validate an efficient and accurate CFD model of a complex flow (steady or unsteady) regime.
3.
Critically evaluate the output from a CFD analysis.
4.
Appreciate the theory underpinning commercial CFD codes.
Module Content
Outline Syllabus:Introduction to CFD
Review the governing equations, N-S equations, continuity, and energy.
Methods for the discretisation of the governing equations.
Methods for handling advection/diffusion problems, upwinding etc.
Solving for pressure fields.
Application of boundary conditions.
The use of appropriate turbulence models in CFD. Time averaging and the
modification of the N-S equations to predict the effects of turbulence (RANS).
Selection of appropriate turbulence model e.g. consideration of a number of different
modelling approaches for example, Prandtl' mixing length model, k-epsilon model,
Reynolds Stress Equation model, (RSM), Large Eddy Simulation (LES) methods.
Modelling of the boundary layer. Law of the wall and use of wall functions.
Basic iterative numerical methods for solving the discretised equations, use of
relaxation, time steps etc.
Meshless techniques.
Critical analysis of CFD results, including errors and uncertainty in CFD calculations
and meshing strategy.
