A New Version of Detached-eddy Simulation, Resistant to Ambiguous Grid Densities (2006, methodology): “Nikitin et al’s [11] exercise showed that WMLES is possible with the DES equations, in the sense that LES content is sustained in the center of the channel, and that wall modeling is achieved, since values of +‖ such as 8,000 are used with results as accurate as they are at lower Reynolds numbers.”
The inner–outer layer interface in large-eddy simulations with wall-layer models (2003, unknown): “function of Re, but only moderately; the cost, in fact, only increases logarithmically (Nikitin et al., 2000).”
Comparison of DES, RANS and LES for the separated flow around a flat plate at high incidence (2003, background): “Furthermore, the spanwise and streamwise resolution do not have to be very high for RANS [10].”
Strategies for turbulence modelling and simulations (2000, methodology): “We show below that it leads to a manageable computing cost even at high Reynolds numbers (Shur et al., 1999; Nikitin et al., 2000).”
Reynolds-stress-constrained large-eddy simulation of wall-bounded turbulent flows (2012, methodology): “This result is believed to be associated with the appearance of a ‘super-buffer layer’ in the vicinity of the RANS/LES interface (Baggett 1998; Nikitin et al. 2000).”
Young-Person''s Guide to Detached-Eddy Simulation Grids (2001, methodology): “Because of this, increasing the Reynolds number by a factor of 10 requires adding about 11 to 13 grid layers [7].”
Large eddy simulation with modeled wall-stress: recent progress and future directions (2016, methodology): “…many proposed versions of hybrid LES/RANS methods over the years, some using the same turbulence model in both regions (e.g., DES in WMLES mode; cf. Nikitin et al., 2000), others using different models in the two regions (among many others, cf. Baurle et al., 2003; Davidson & Peng, 2003; Temmerman…”
Hybrid LES‐RANS modelling: a one‐equation SGS model combined with a k–ω model for predicting recirculating flows (2003, background): “channel ows [30], shows a fairly strong dependency on the grid arrangement in the wall-parallel directions.”
Wall-modeling in large eddy simulation: Length scales, grid resolution, and accuracy (2012, background): “Nikitin et al. (2000) showed clearly how DES is affected by an artificial buffer layer that results in 10-15% underprediction of the wall shear stress τw (i.e., the skin friction).”
