INDICATIVE CONTENT
This module provides a strong understanding of fluid flow simulations and associated approaches to successful CFD modelling. During this module, students will learn about conservation equations (continuity and momentum) and its corresponding general scalar transports. They will learn about different discretisation schemes (e.g. central, upwind, exponential, Flux limited etc.) as well as scheme characteristics. Students will also learn about iterative numerical approaches (e.g. Gauss-Jacobi, Gauss Sidel etc) for solving set of equations. Students will apply discretisation schemes to discretise scalar transport equations for diffusion and advection problems and numerically solve them with the help of iterative numerical approaches. This will be followed by learning about how to deal with pressure velocity coupling with staggered and non-staggered grid approaches as well as learning about the pressure-correction methods (SIMPLE and PISO). Students will also learn about how to numerically deal with unsteady differential equations and solving transient CFD problems. Different types of cells and meshes, the impact of mesh on CFD simulation and mesh quality criteria will be discussed. Students will also learn about different boundary conditions definitions and their applications in dealing with advanced CFD simulations for getting better CFD results. Post processing of CFD results obtained from simulations will also be discussed.
In this module, students practice the theory of the aforementioned topics during lecture classes while in practical sessions they will learn to apply the discussed theory in practice to solve an advanced CFD problem with a commercial CFD tool and conduct a project.
