Synthetic turbulence inflow tests
|
|
======================
|
|
|
|
The following three synthetic turbulence inflow boundary conditions are
|
|
examined through a single-cell-domain smooth-wall plane channel flow setup:
|
|
|
|
- turbulentDFSEMInlet
|
|
- turbulentDigitalFilterInlet variant=digitalFilter
|
|
- turbulentDigitalFilterInlet variant=reducedDigitalFilter
|
|
|
|
The input statistics are obtained from:
|
|
|
|
Moser, Kim & Mansour
|
|
"DNS of Turbulent Channel Flow up to Re_tau=590",
|
|
Physics of Fluids (1999) vol 11, 943-945.
|
|
doi.org/10.1063/1.869966
|
|
|
|
from which the input first-/second-order turbulence statistics data for the
|
|
smooth-wall plane channel flow at Re=395 were used.
|
|
|
|
The data is available online from (Retrieved: 21-06-2019):

Serial executing:
|
|
|
|
./Allrun
|
|
|
|
Parallel (decompositionMethod=scotch) executing:
|
|
|
|
./Allrunparallel
|
|
|
|
Both scripts run the test case, and collect the OpenFOAM samples, and plots into
|
|
the 'results' directory.
