Abstract
A topic of obvious interest is the interaction between the vortex wake behind bluff bodies and nearby objects, in particular plane surfaces. At present the most detailed studies in flows such as these have been on the characteristics of the velocity field of the vortices [1, 2]. The main topic of attention in what follows is pressure pulsations on a wall caused by separation of vortices from an adjacent cylinder. This problem is especially important for the determination of vibrations and noises due to bodies located on the rigid boundary of the flow.
