Large-eddy simulation and experimental study of heat transfer, nitric oxide emissions and combustion instability in a swirled turbulent high-pressure burner (2007, background): “Convective heat transfer modelling The description of wall mechanisms is the weak point of LES (Sagaut 2000; Cabot & Moin 2000): in most reactive LES in complex geometries, the resolution of the boundary layer region is computationally out of reach.”
Advances in turbulent flow computations using high-resolution methods (2003, neutral): “, [16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26] used in LES [28, 29].”
Computation of a high Reynolds number jet and its radiated noise using large eddy simulation based on explicit filtering (2006, background): “The modelling of the subgrid stress tensor has been debated for a long time, see discussions in recent reviews [20–23].”
Three-dimensional vortex structures under breaking waves (2005, methodology): “We considered the corresponding turbulent energy in the same manner as Sagaut (2001). Thus, the instantaneous GS velocity ui is defined to be ui = 〈ui〉 + ui ′, (A 1) where the phase-averaged GS velocity is 〈ui〉, the fluctuation is ui ′.”
Large-Eddy Simulation Inflow Conditions for Coupling with Reynolds-Averaged Flow Solvers (2004, background): “In the case of turbulent boundary layers, LES is usually too expensive, since the small turbulent scales, which have to be resolved near the wall, require in very fine meshes and very small time steps [15].”
