Abstract

The interference of flow around two circular cylinders forming a cross can be considered as an element of a gauze screen or an offshore structure. The most important feature of the interference was found to be a significant increase of local drag coefficient due to the symmetric formation of secondary flow patterns. The pressure distribution measured around both cylinders at various spanwise stations was distinctly different for the two cylinders in the region of interference. A strong secondary flow was found behind the upstream cylinder and in front of the downstream cylinder. The secondary flow distorted and displaced the separation streamlines on the upstream and downstream cylinders. This has been verified by oil-film flow visualization.
