I think you would be best served by a 2-D flow visualizer of which
there are several out there. I don't think hand computation of
reasonable values for lift n drag are reasonable objectives.

As for the flow visualisers: I'll be grateful for a suggestion of one I
can run from the Linux command line.

Thanks again,

I tried an early version of Drela's Xfoil. It is available now in
several suitable flavors he

Can't remember whether these distributions include the data for the many
foils held by U.Illinois. Probably do?
