Abstract
The turbulent flow around a generic configuration of a landing gear (’the tandem cylinder’) is simulated and analysed physically at Re = 1.66x105, by means of hybrid RANS-LES turbulence modelling approaches. In the present study, the Delayed Detached Eddy Simulation (DDES) approach has been employed. The DDES-OES modelling has been considered, especially involving turbulence length scale reconsiderations in the statistical part, by means of the Organised Eddy Simulation, (OES), to take into account non-equilibrium turbulence effects. The DDES-k-ω SST model is also considered. The results, obtained by means of two different time steps are compared with experiments carried out at the NASA-Langley Research Centre in the context of ATAAC EU-program in which the tandem cylinders is one of the ‘stepping stones’. In the present study, the benefits of these hybrid approaches have been discussed for capturing the vortex dynamics and frequency modes responsible for aerodynamic noise production in the context of landing gear configurations.
