The case considered is the 1d solution of fully-developed
turbulent flow in a plane closed channel at a Re=1.E5. The
solution is performed by use of the single-slab solver which
computes the pressure drop for the specified mass flow rate.
Calculations are made with the high-Re forms of the k-e model,
the Chen-Kim k-e model (the default run), the RNG k-e model,
the Wilcox 1988 & 2008 k-W modelS, and the Menter Baseline
& SST k-w models. For this case all models produce very similar
results, and the comparison between measured and computed
friction factors f and velocity-defect parameters vdp are
given below:
f vdp
Data 0.0156 2.32
Standard k-e 0.0160 2.25
Chen-Kim k-e 0.0157 2.27
RNG k-e model 0.0154 2.5
Wilcox 1988 k-w model 0.0166 2.0
Wilcox 2008 k-w model 0.0161 2.09
Menter k-w model 0.0166 2.0
k-w SST model 0.0158 2.05
where f=8.*(wstar/wbulk)**2 and and vdp=(wcl-wbulk)/wstar.
