The objectives of this module are to provide a thorough description of the mathematical methods and numerical techniques used in Computational Fluid Dynamics (CFD) and to provide a practical experience in the use of a state of the art commercial modelling software. The module covers incompressible laminar and turbulent flow with heat transfer and involves both theoretical exercises and practical computational modelling of fluid and heat transfer problems.

Learning Outcomes

1. Interprete the theoretical foundations of core numerical methods and mathematical models found in Computational Fluid Dynamics
2. Select appropriate governing equation to model specific fluid or heat transfer problem and make appropriate simplification to allow discretisation and solution
3. Formulate and set-up CFD models for the solution of simple but realistic thermo-fluid problems
4. Appreciate the limitations and capabilities of the main models and solution methods available with state of the art CFD Softwares based on the Finite Volume Method
5. Quantify the order of accuracy of a CFD model based on the choice of discretisation scheme
6. Evaluate critically the quality of a mesh, model set-up and results
7. Propose improvements to existing model setup with a view to adressing specific issues including limited computational power or memory
8. Demonstrate the importance of careful validation by comparison with experimental and/or analytical solutions
