FoilSimU III includes all of the options of the original FoilSim III
plus some additional input and output panels.
These panels are made available so that you can study the details of the
used in the Kutta-Joukowski analysis.
In the analysis, flow around a cylinder is mapped into
flow around an airfoil. Using the Input Push Buttons
on the Control Panel,
you can display a generating plane input panel.
The panel contains four input variables which
control the size and location of the generating cylinder
relative to the poles of the transformation, and the
strength of the
which is embedded in the airfoil.
According to the
Kutta condition of the analysis,
the strength of the vortex is
set to bring the aft stagnation point to the trailing edge.
With this version of FoilSim III, you can turn the Kutta condition
off by using the Analysis input panel to
study the effect.
A graph of the flow in the generating cylinder plane is
also available using the
Plot Selection input panel.
