Abstract
The vorticity evolution induced by a source doubler that turns out in a two-dimensional shear flow is investigated analytically for an incom pressible inviscid fluid. The velocity field is obtained by use of the Linearized Euler equation and the equation of continuity. The process of the closed vortex formation around the doubler and the interaction of these closed vortex are shown by investigating the time developmen t of the disturbance vorticity.
