Here's a link to animated visualizations of the flow past a wing:http://www.av8n.com/irro/- click the flag of your favored language to

I've never really liked that Joukowski transform stuff. The arbitrary
definition of circulation worries me, and anyway no real wing behaves
anything like that. It's a fair way of visualising the flow, roughly,
but I prefer to jump straight into circulation theory and model my
wings as vortices.
