Abstract
In a hierarchical fashion both the handling of turbulence and geometry are considered. The latter is necessary to help more economically deal with the increasingly coupled nature of many aerodynamic problems and also the drive towards considering ever increasing levels of geometrical complexity. The hybridization of RANS (Reynolds Averaged Navier-Stokes) and LES (Large Eddy Simulation), in various forms is explored. In relation to this, a taxonomy is presented. These aspects have all been presented here with a focus more on turbomachinery. The design needs for future engines is explored and it is discussed how these need to be met in a very integrated way, encompassing global installations all the way to avionics systems. However, it is believed that the applicability of these ideas goes beyond turbomachinery and is relevant to many other industrial applications. It is expected that the combination of these ideas will allow engineers to appropriately perform eddy resolving simulations in systems where there is significant aerodynamic coupling and a high level of geometrical complexity. The proposed unified framework could be exploited all the way through initial fast preliminary design to final numerical test involving various bespoke combinations of hierarchical components.
