Large eddy simulations and subgrid scale modelling of turbulent shear flows

Pierre Comte, Laboratoire d'Etudes Aérodynamiques (LEA), Poitiers, France

Large-Eddy Simulation has proved to be a very useful and promising method to better understand the dynamics of organized vortices and match the statistics of an increasing range of shear flows, ranging from academic to industrial configurations. The underlying formalism will be introduced in the first talk, together with the rationale behind the development of some succesful subrid-scale models. Examples of applications will be presented, with an increasing level of flow complexity (mixing layers, boundary layers, pulsating or supersonic channel flow, transonic cavity flow and its control).
