The focus of this paper is on the increasingly important role played by highly-resolved LES in supporting the development, improvement and validation of statistical RANS closures. This is illustrated by way of four recent studies by the writer's group, directed towards separation from curved surfaces, the interaction between structurally disparate shear layers, bypass transition and active flow control of separation.

Keywords:  LES; RANS; Turbulence modelling; A-priori testing; Non-linear eddy-viscosity models; Reynolds-stress models
