This course introduces Computational Fluid Dynamics (CFD), which enables the accurate simulation of realistic fluid processes, utilising modern computing power. This extends the capability of engineers beyond the simplified models (as taught in other courses) that are commonly used in industry.

This course covers the theoretical and practical components of the CFD framework to enable the student to simulate real fluid flow problems which are more complex than solved in prior undergraduate courses in fluid mechanics. Students will become fluent in conducting each stage of the process so that they can solve practical problems using advanced analysis. These problems can be simple fluid flow (either liquid or gas), involve heat transfer, chemical reactions and/or multiple phases [i.e. a flow containing a mixture of gas, liquid and solid (normally solid particles)]. Problems which students will analyse will be drawn from cases such as: pipe flows (gaseous or liquid), airflows over vehicles (e.g. cars, trucks and aircraft), wind loading on structures, hydraulic flows (e.g. rivers and water treatment plants), heat exchangers and combustion (e.g. engines and furnaces). Students who wish to simulate combustion cases will have a stronger foundation if they have also completed MEC5105 Combustion; they will also have the opportunity to perform more detailed and accurate combustion simulations if they complete MEC5105 Combustion in the future.

On successful completion of this course students should be able to:

1. characterise the transport equations for fluid flow and how they can be solved;
2. construct a model for the fluid flow problem that needs to be solved;
3. evaluate different CFD programs and discretise the domain to produce a mesh which will enable an accurate solution for the chosen program;
4. appraise the models for physical phenomena;
5. appraise the numerical methods for the discretisation of the transport equations and generate accurate results;
6. critically evaluate the results of simulations.
