This paper investigates hybrid RANS-LES turbulence modelling in real-life aeroelastic problems. The analysis is based on the author’s calculations carried out in the framework of the Second Aeroelastic Prediction Workshop, those requested by the GARTEUR Action Group AG54, codenamed RALESIN (www.ag54-garteur.online), and the assessment of a few additional test cases, introduced especially to improve the understanding of hybrid models. Unsurprisingly, the analysis shows that hybrid turbulent methods can be very accurate but that quality may quickly degrade as the calculations parameters (spatial and temporal resolution, subgrid filter and turbulence model) move away from optimum values.
