Recent Trends in Computation of Turbulent Jet Impingement Heat Transfer (2012, methodology): “[ 45 ] developed a method where fluctuations are generated by synthesizing turbulence rather than adding random fluctuations.”
Unsteady effects of strong shock-wave/boundary-layer interaction at high Reynolds number (2017, methodology): “boundary condition is used (Klein et al. 2003), for which first and second order statistical moments have been prescribed through a precursor zero-pressure gradient temporal boundary-layer simulation with target TBL thickness of δ0 and otherwise same flow conditions as the SWBLI simulations.”
Conditional Moment Closure for Large Eddy Simulations (2005, background): “This may be due to the uncorrelated initial inflow conditions, which can affect second moment statistics [ 50 ].”

Flow around a cube in a turbulent boundary layer: LES and experiment (2009, methodology): “An alternative approach would be to use one of the many digital filter methods, in which inlet turbulence of the required intensity and spatial scale (in all coordinate directions) is produced by carefully massaging sets of random numbers (e.g. Klein et al. 2003).”

Confinement effects in shock wave/turbulent boundary layer interactions through wall-modelled large-eddy simulations (2014, neutral): “…Xie & Castro (2008), the integral length scale in the streamwise coordinate is transformed into a Lagrangian time scale to enforce the two-point correlation in the direction normal to the inflow plane, avoiding the filtering of a 3D field needed in the original method by Klein et al. (2003).”
