The present paper describes the observation of horseshoe vortex around the jucnture, between flat plate and circular cylinder. In the case of inclined cylinder, the three-dimensional separation region in front of the body is smaller and the flow stability is stable. The milk-painting method is useful for visualizing the flow field in laminar flow and also the limiting streamline in turbulent flow. The oil-film method and the tracer method are also applied for observation of this flow.
