The following three synthetic turbulence inflow boundary conditions are examined through single-cell-domain smooth-wall plane channel flow setup: - turbulentDFSEMInlet - turbulentDigitalFilterInlet variant=digitalFilter - turbulentDigitalFilterInlet variant=reducedDigitalFilter The examinations are performed in terms of the first-/second-order turbulence statistics provided by (Moser et al., (1999)) doi.org/10.1063/1.869966 from smooth-wall plane channel flow direct numerical simulations at Re=395.
