Presented here are NEWPAN results compared with experimental data for
a model that formed a key part of the UK National High-Lift Program.
Results shown here are for an incidence of 10.1 degrees and a Mach
number of 0.2.
The basic geometry is illustrated here via the surface panelling.
This second view of the panelling includes the wakes generated for
this case, in their initial unrelaxed form.
Pressure results (Cp) are shown for the solution, as a
gouraud shaded colour map.
Once again, for clarity, wakes are only shown on the second image.
Finally, sectional pressure plots at 4 spanwise stations are
shown. The line is the Newpan solution, the stars are pressure tappings
from wind tunnel analysis. NEWPAN provided excellent correlation with these test
results. This included correct capturing of the U-shaped upper surface
flap pressure distribution at its outboard end, which is due to the
flap tip vortex rollup, and which other codes failed to predict.
