Pre-requisite qualifications

In order to study this module it is essential that fluid mechanics and thermodynamics have been studied as prerequisites to this module. It is expected that students will be familiar with the following areas: conservation laws, key parameters (e.g. pressure coefficient, Reynolds/Peclet numbers etc), basics of flow physics (e.g. development of boundary layers, flow separation, recirculation etc), turbulence/transitional/laminar flows, lift/drag/side force coefficients and knowledge of thermodynamics including fundamentals of heat transfer (e.g. conduction/convection/radiation).

This module is not approved as an Elective

Module summary

This module provides the basic theoretical and practical knowledge to allow a student to competently perform Computational Fluid Dynamics (CFD) analysis using commercial software packages used in industry. This is reinforced through a series of practical tasks modelling flows of varying types and complexity. These tasks relate to various engineering applications including aeronautics, mechanical and civil engineering. Participants should be able to apply this knowledge to other application areas including automotive, wind, biomedical and oil ang gas engineering.

Objectives


Learning outcomes
On completion of this module, the student will be able to:
1. Understand the governing equations for fluid dynamics and appreciate the limitations of numerical methods/algorithms required for solving them;
2. Appreciate the challenges and limitations of CFD application including the importance of verification and validation;
3. Evaluate and select the most appropriate solution strategy for a particular application;
4. Undertake the simulation and analysis of practical problems using a commercial CFD package and critically assess the output solution.
