ABSTRACT
In the field of fluid mechanics the governing equations are based on conservation principles: mass, momentum-energy. Computational Fluid Dynamics (CFD) has made significant progress for solving the Navier-Stokes partial differential equations. Various discretisation methods and numerical schemes have been developed. The most commonly used schemes in the field of CFD are the Finite Difference Method, Finite Volume Method (FVM) and the Finite Element Method. The FVM approach was used in this thesis by performing numerical simulations using the ANSYS Fluent® software. The integral formulation of the conservation laws is the basis of FVM schemes. In CFD three basic types of grids can be generated depending on the application: structured grids, unstructured grids and a combination of both, hybrid grids. The control volume for the fluid is defined over the geometry of the model. FVM methods enable a straightforward derivation of the cell-centred FVM equations.
