Learning Strategies
This module will enable students to gain understanding, apply knowledge, analyse and evaluate problems and create solutions through a variety of activities, including:
• Taught Lectures
• Use of software packages Ansys/ICEM and Ansys/Fluent
Laboratory/Tutorial taking place in school laboratories where software related demonstrations, practical exercises and formal assignments will be undertaken.

MODULE INDICATIVE CONTENT
This module provides a strong understanding of fluid flow simulation on which most CFD simulation are based. During this module, you will be trained to use advanced flow simulation software for CFD calculations. The you will learn about the key element in computational fluid dynamics simulations such as conservation laws and equations, consistency, stability and convergence which is applicable to a wide range of fluid flows, wind speeds and compressible/non-compressible problems. You will also learn about boundary conditions and mesh generation/refinement in the computational domain which will facilitate them with strong tools for CFD simulation of complicated engineering problems. They will learn a wide range of numerical techniques and in the end, they will carry out a step by step CFD simulation of a compressible/incompressible steady flow and they will learn about post processing of CFD problems.
