A hybrid RANS-LES approach with delayed-DES and wall-modelled LES capabilities (2008, background): “…substantial outside information such as fields from wallresolved LES or DNS runs (e.g., Davidson and Dahlstrom, 2005) or synthetic turbulence (e.g., Davidson and Billson, 2006) at the RANS-LES interface, and/or require averages in the wall-parallel directions to define intermediate quantities…”
Large Eddy Simulations: How to evaluate resolution (2009, background): “The grid resolution in DNS and wall-resolved LES is dictated by the necessity of resolving the energy-generating process high-speed inrushes and low-speed ejections (Robinson, 1991) in the viscous sub-layer and the buffer layer, often called the streak process.”
Large eddy simulation with modeled wall-stress: recent progress and future directions (2016, background): “Small-scale forcing has been used in quite a few studies (cf. Piomelli et al., 2003; Davidson & Dahlström, 2005; Davidson & Billson, 2006; Keating & Piomelli, 2006), with generally successful results in the sense of a reduced loglayer mismatch.”
A New Divergence Free Synthetic Eddy Method for the Reproduction of Inlet Flow Conditions for LES (2013, methodology): “[7], the method of Sergent [14] (referred to as VORTEX) and the method of Davidson and Billson [3] (referred to as DB).”
