摘要：
In the turbulent wake behind an upstream cylinder in a uniform flow, the downstream cylinder was set in the form of an intersection with the upstream cylinder. A secondary flow was found behind both cylinders. The important feature was found to be an increase of base pressure due to the formation of secondary flow patterns. The flow pattern has been verified by oil-film and tufts flow visualization. The base pressure at various spanwise stations for both cylinders was measured. Then, the relationship between the secondary flow and the base pressure was studied.
