Detached Eddy Simulation for Industrial Aerodynamics
The DESider project is motivated by the increasing demand of the European aerospace industries to improve their CFD-aided design procedure and analysis on turbulent unsteady aerodynamic flows. Recent modelling approaches such as DES, hybrid RANS-LES, embedded LES – summarised as RANS-LES methods - but also URANS have not yet reached maturity as general predictive tools for industrial CFD with a “sensible” reliability.
Thus the major aim is to overcome known weaknesses in the different approaches - in order to support the European aeronautics industry by providing method(s) with increased predictive accuracy for flows exhibiting separation, i.e. emphasis must be placed on the enhancement of both the modelling capability of RANS-LES methods and the alleviation of computational costs. In that respect, DESider will close the gap between RANS and LES but is not treating LES as a stand-alone method – as it is known that full LES for practical use will not be available in the next decades.
