Large Eddy Simulation is a relatively new and still evolving computatio- nal strategy for predicting turbulent flows. It is now widely used in research to elucidate fundamental interactions in physics of turbulence, to predict phe- nomena which are closely linked to the unsteady features of turbulence and to create data bases against which statistical closure models can be asses- sed. However, its applicability to complex industrial flows, to which statisti- cal models are applied routinely, has not been established with any degree of confidence. There is, in particular, a question mark...
