Abstract
In recent years, the interest for composite RANS-LES models, wall-modelled LES approaches and their application to the high-fidelity simulation of turbulent flows has been growing rapidly. This interest is motivated by the need to overcome the well known limitations of RANS models in simulating massively separated flows and to mitigate the cost of a full LES, which nowadays can be still not feasible for many industrial applications.
