Visualization of Separating Stokes Flows

This paper provides photographs of separating Stokes flows. Silicone oil and glycerine were used as the working fluid. The aluminum powder method and the glass beads method were used for flow visualization. The flows studied are flows around bodies placed in a uniform flow, flows past bodies placed near a plane wall, flows past a fence, flows past a step, flows past a wall cavity, and flows near a sharp corner. It is found that there is a remarkable agreement between the experimental results and the theoretical ones.
