Progress in Hybrid Temporal LES (plenary lecture)

Abstract : In order to favour the modelling of the subgrid stresses in continuous hybrid RANS/LES methods, the comparison of the solutions with experimental or DNS databases, and eventually the understanding of the phenomenology observed in the resolved motion, defining a rigorous formalism for such methods is highly desirable. Empirical methods to bridge RANS and LES suffer from the fact that RANS and LES are based on generally inconsistent operators, statistical averaging and spatial filtering, respectively [9]. The present paper summarises recent work that tries to reconcile the two methodologies by defining consistent operators, based on temporal filtering, and provides examples of HTLES (Hybrid Temporal LES) models that can be derived based on this formalism.
