The cylinders were aligned with the axis normal to both the flat plate and the free stream. The time-mean surface pressures on the cylinders and the frequency of the vortex shedding in the direction of the cylinder axis were measured. The flow patterns on the cylinder were visualized using an oil-film technique and the flow visualization around the cylinders was performed by the liquid-parafine-mist technique. The flow patterns near the end of the cylinder were essentially different from two-dimensional flow. The flow passing along the end surface of the upstream cylinder became oscillating flow at the frequency lower than that of Karman vortex.
