TALK=T;RUN(1,1)
DISPLAY
The problem considered is plane turbulent couette flow in a
channel at a Reynolds number of 1.E5, as described in detail
for library case T100.
The turbulence is simulated by use of the Prandtl mixing length
model with Nikuradse's prescription of the mixing length. If
REYLOW=T in the Q1 file, the calculation integrates down to both
walls by using van Driest's viscous-damping extension to the
mixing length. The solution is performed one-dimensionally by use
of the single-slab solver. A non-uniform grid is employed so as
to concentrate cells very close to the walls.
