Numerical simulation is used to optimise designs and to predict the behaviour of complex systems. In most cases it is the only predictive method available to the designer, short of constructing and building a full prototype. It follows, therefore, that a lot of confidence is placed on the results of simulations and significant costs and time penalties are incurred if predictions are incorrect. Hence, it is essential that the results of numerical simulations are tested against careful measurements and a validation procedure is followed throughout the lifetime of any predictive code. The purpose of this paper is to show results of some of these tests and the level of agreement with experiments which can be expected.
