• STUDY ON THE AERODYNAMIC OSCILLATION OF A CIRCULAR CYLINDER IN THE WAKE OF RECTANGULAR CYLINDERS

抄録

Wake excitation is an important problem for parallel circular cylinders. It is well known that this phenomenon is caused by the interaction between the downstream cylinder and the wake flow of the upstream cylinder. Therefore, this phenomenon is affected by the Reynolds number. In this study, to remove the effect of Re-number, some kinds of rectangular cylinders were used instead of the upstream circular cylinder. Wind tunnel test were carried out and it was found that the downstream cylinder was excited even if the width of the upstream wake was very small in comparison with the diameter of the downstream cylinder. The width and velocity defect of wake of the upstream cylinder play important role for the oscillation.
