There are many papers concerned with flow visualization around a circular cylinder, but most of them reported the flow that flow boundary did not affect the flow pattern around a circular cylinder. Now since offshore structures have been or will be built: for example, the Kansai International Airport and Chubu New International Airport (tentative name) are to be constructed in the near future. It is necessary to investigate the flow field around a horizontal circular cylinder suffered from bed boundary effects. In this paper, changing the clearance ,e, between cylinder and bed. We report the results of flow visualization around a horizontal circular cylinder immersed in open channel. Especially we paid attention to the accuracy of velocity vector at nodal point, applying to the variational principle to continuity equation.
