Abstract
Around 1930 Ludwig Prandtl and his colleagues O. Tietjens and W. Müller published two films with visualizations of flows around surface piercing obstacles to illustrate the unsteady process of flow separation. These visualizations were achieved by recording the motion of fine particles sprinkled onto the water surface in water channels. The resulting images meet the relevant criteria of properly seeded PIV recordings and can be readily processed using modern PIV algorithms. This allows the visualization of flow quantities (e.g. vorticity) that were previously unaccessible. The proposed movie gallery contribution will consist of selected original film sequences accompanied by corresponding visualization of PIV derived data.
