a body immersed into a liquid with a flow circulation around it (the Kutta­ Joukowski theorem). An example of this is the lift force on an airplane wing. The key role of the Magnus force in vortex dynamics became clear from the very beginning of studying superfluid hydrodynamics. In the pioneer ar­ ticle on the subject Hall and Vinen [2] defined the superfluid Magnus force as a force between

5/12/2010 · Despite its incomplete story, the “heuristic derivation” of the Kutta–Joukowski theorem brings me back to my intuition aquired when I was playing with toy planes as a kid. It had always been obvious for me that a toy plane was “lifted from below”, or in other terms that it was an action-reaction story. It seems that the Bernoulli’s principle is precisely telling that relation between the
Kutta-Zhukovsky suggested that the circulation around the wing section was balanced by a counter-rotating so-called starting vortex behind the wing as shown in the figure, giving zero total circulation according to Kelvin’s theorem. KuttaZhukovsky’s formula for lift (proportional to the angle of attack) agreed reasonably well with observations for long wings and small angles of attack, but
