| Abstract/Summary |
In this thesis the validation of a computational fluid dynamics (CFD) code against published experimental data and alternative CFD results is explored. Six case studies are presented with flow speeds ranging from mid supersonic to hypersonic. The studies include complex compressible flow phenomena such as the interaction of shockwaves with boundary layers, vortices and other shockwaves. Two of the six validation cases also consider complex thermodynamic behaviour such as vibrational and chemical nonequilibrium. The problems chosen are limited in scope to flows which are planar or axisymmetric and remain laminar throughout the region of flow studied. This allows the studies to focus on simulating the fundamental behaviour of the flow without the added complication of turbulence or the need for large scale computing facilities. The problems which arose during the validation studies and a background to why they occurred and, wherever possible, strategies to avoid their occurrence are discussed. General modelling strategies in compressible CFD are also discussed. In this thesis the software suite CFD-FASTRAN is used to construct and analyse the CFD models. The material presented in this thesis is however general such that users of similar packages should find the thesis beneficial.
