In this thesis the author presents two areas of work; exploring the integration of Computational
Fluid Dynamics (CFD) into engine design for Jaguar Cars Ltd and developing a novel
'mesh construction' method for making mesh generation both easy and fast.
It is concluded that Jaguar can use CFD in the evaluation stage of the engine design process,
although not in the concept stage of design. The CFD predictions are shown to be useful for
detecting flow related faults and determining the general flow trends, but they should not be
used as an absolute measure of the flow variables. The author has determined an efficient
method for obtaining good quality meshes using commercial modelling and mesh generation
software which requires a skilled CFD analyst. Steady flow analysis of an engine port and
cylinder design could currently be completed in about six weeks using a high-powered workstation.
The author recommends dedicated workstations for CFD analysis and training Jaguar's
draughtsmen to create CAD models with computer analysis requirements in mind.
The author's mesh construction program automatically joins two overlapping meshes or cuts
one mesh from another. Whilst the program works well on the test cases considered, it is not
at a stage for commercial exploitation. Further development is therefore recommended.
