An Attempt to Assess the Quality of Large Eddy Simulations in the Context of Implicit Filtering (2005, result): “[ 5 , 6]. Also Ribault et al. [25] report similar findings for a plane jet.”
Explicit Filtering and Reconstruction Turbulence Modeling for Large-Eddy Simulation of Neutral Boundary Layer Flow (2005, methodology): “In addition, there are errors due to aliasing effects, though these are not as important in finite-difference as in spectral codes (Chow and Moin 2003).”
The Effect of Mesh Resolution on Convective Boundary Layer Statistics and Structures Generated by Large-Eddy Simulation (2011, background): “discretization errors are intertwined since both depend explicitly on the mesh spacing (Chow and Moin 2003; Meyers et al. 2007; Geurts and Fröhlich 2002).”
A posteriori study using a DNS database describing fluid disintegration and binary-species mixing under supercritical pressure: heptane and nitrogen (2010, background): “For a sixth-order Padé scheme, this ratio must be ̄ 2 xLES (Ghosal 1996; Chow & Moin 2003), and the present choice is ̄ = 2 xLES , meaning that the smallest resolved eddy is represented by at least two grid points.”
High order conservative finite difference scheme for variable density low Mach number turbulent flows (2007, methodology): “In order to further analyze the a priori properties of these schemes, the study of aliasing errors proposed by Kravchenko and Moin [2] is extended here to include the fourth and sixth order schemes.”
