Extract
Cylindrical arrays subjected to external flow have been the subject of considerable study in recent years. Much of this study is concerned with a solitary cylinder or cylinder arrays involving many cylinders with the same diameters. Common structures however have cylinders with different diameters. For example, in a reactor, there are small diameter cylinders amongst large ones. In this situation, the dynamic behaviour of the cylinders are different from the cylinder arrays of equal diameters. Since the case of a pair of parallel circular cylinders in a cross-flow constitutes the simplest configuration, its study should be of importance in the understanding of more complicated situations. Various modes of oscillations associated with two interfering cylinders may be found in review papers by Zdravkovich. This note presents some laboratory observations of the response of a rigid twodimensional flexibly mounted smooth circular cylinder, with vibrations restricted to a plane normal to the incident flow, as induced by the vicinity of a rigid parallel circular cylinder of different diameter.
