摘要：

The flow over two circulars was studied with the cylinders in a staggered arrangement. Lock-in occurred in which the frequency of shedding from the downstream cylinder remained at half the frequency of shedding from the upstream cylinder over a range of the latter frequency. When the interference of the flow over the downstream cylinder due to the upstream cylinder was small, lock-in resulted in a reduction in the downstream cylinder's base pressure. When the interference was large lock-in depended on the Reynolds number.
