Hybrid LES-RANS using synthesized turbulent fluctuations for forcing in the interface region (2006, methodology): “In agreement with the findings of Piomelli et al. (2003), forcing increases the resolved shear stress, thereby reducing the centerline and bulk velocity.”
Reynolds-stress-constrained large-eddy simulation of wall-bounded turbulent flows (2012, background): “1 to guarantee an accurate value of wall shear stress τw (Piomelli & Balaras 2002; Piomelli et al. 2003).”
Cascades and transitions in turbulent flows (2018, background): “The literature on the subject is vast, starting from the early works in [537, 543, 544] and including recent attempts based on fully reversible closures (see [545] and reference therein).”
A New Version of Detached-eddy Simulation, Resistant to Ambiguous Grid Densities (2006, background): “A tentative solution is to stimulate this region artificially [24].”
Wall-modeling in large eddy simulation: Length scales, grid resolution, and accuracy (2012, methodology): “Later studies have shown how artificial forcing can remove this error, but at the price of introducing additional modeling parameters that must be tuned (cf. Piomelli et al. 2003; Larsson et al. 2007).”
Wall-layer models for large-eddy simulations (2008, background): “Piomelli [22].”
Hybrid LES/RANS methods for the simulation of turbulent flows (2008, methodology): “[71] tackled the problem of the spurious buffer layer by supplementing the method with a stochastic forcing term.”
Large-Eddy Simulation: Current Capabilities, Recommended Practices, and Future Research (2009, methodology): “These include techniques that introduce fluctuations into the LES region [38–41] and incorporate mean stresses from the time-averaged LES back into the RANS regions [42,43].”
Large eddy simulation with modeled wall-stress: recent progress and future directions (2016, background): “The question of the required resolution in the inner layer is quite straightforward for hybrid LES/RANS methods (no limit on wall-parallel∆x and ∆z; resolve wall-normal∆y just like in RANS), but is deeper and more important than it appears at first sight for wall-stress-modeled LES.”
Large Eddy Simulations: How to evaluate resolution (2009, background): “11, 12, the two-point correlations increase when the grid is coarsened (Cases 2∆x and 2∆z) because the smaller scales are not resolved; for these coarse resolutions the streamwise two-point correlations are dominated by the “superstreaks” (Piomelli et al., 2003; Keating and Piomelli, 2006).”
