Elements of computational fluid dynamics on block structured grids using implicit solvers

This paper reviews computational #uid dynamics (CFD) for aerodynamic applications. The key elements of a rigorous CFD analysis are discussed. Modelling issues are summarised and the state of modern discretisation schemes considered. Implicit solution schemes are discussed in some detail, as is multiblock grid generation. The cost and availability of computing power is described in the context of cluster computing and its importance for CFD. Several complex applications are then considered in light of these simulation components. Veri"cation and validation is presented for each application and the important #ow mechanisms are shown through the use of the simulation results. The applications considered are: cavity #ow, spiked body supersonic #ow, underexpanded jet shock wave hysteresis, slender body aerodynamics and wing #utter. As a whole the paper aims to show the current strengths and limitations of CFD and the conclusions suggest a way of enhancing the usefulness of #ow simulation for industrial class problems.
