Abstract

The quest for unlimited geometric flexibility as a prerequisite to the integration of CFD into the design cycle for real engineering components has led, over the past few years, to the development of flexible three-dimensional multi-block and unstructured-grid schemes supported by sophisticated gridgeneration techniques. Current capabilities are such that quantitatively credible representations of flows around and within complex geometries can be attained by numerical computations, provided effects arising from turbulent transport do not contribute materially to the flow properties that govern important operational characteristics of the associated engineering configuration. This usually means that the boundary layers developing on its surface are thin and attached, and losses arising from turbulence are low and confined to a minor proportion of the whole flow domain. In contrast, for configurations such as wing-fuselage junctions and multi-stage turbomachines operating close to their ‘off-design’ conditions, the representation of turbulence effects can be of crucial importance to the predictive realism.
