000014455 520__ $$2eng$$aThe rotor-oscillator flow consists in rotating a cylinder parallel to a wall in a viscous fluid to generate a separation. If in addition the cylinder is translated along the wall with a given velocity profile, the separation profile becomes unsteady and can be easily manipulated. Particle image velocimetry is used to study different scenario of two-dimensional fixed and moving separation. For the fixed case, existing formulae to compute the profile of the on-wall separation are validated. For the moving case, the separation point coincides with a Lagrangian saddle-point moving inside the flow and a method is proposed to compute the stable and unstable manifolds to which it belongs.
