摘要An experimental study of the interference effects between two and three cylinders of finite height immersed in a turbulent boundary layer at subcritical Reynolds numbers has been conducted in a boundary layer wind tunnel, utilizing a pneumatic averaging manifold system to measure the fluctuating force at various levels. Measurements of mean drag and lift force coefficients, mode-generalized RMS drag and lift force coefficients, and mode-generalized drag and lift force spectra, for a range of cylinder spacings, configurations, and various angles of attack, are presented. The interference levels observed were found to depend strongly on the spacing, angle of attack, and the arrangement of the cylinders with respect to each other. The investigation of these relationships for finite cylinders should prove insightful to those interested in such phenomena.
