초록

Flow patterns are very complex and interactive between cylinders. The patterns are turbulent and non-linear caused by varous factors. In this paper, flow patterns and pressure gradient around vertical cylinders were investigated by experient. Changing gaps between cylinders the flow patterns are measusred at a fixed coming velocity. Flwo patterns showd very complex and closely related to the coming velocity and cylinder space. The pressure gradient around the flow field is observed by twelve hole pitot tubes and manometer. The experimental results using pitot tube showed in a good agreement with results of previous study by others.
