This experimental study is carried out the impacts of a downstream cylinder in the wake change on upstream object"s diameter. The V-shaped object is located in the upstream of the test section and the circular cylinder included load-cell is located in the downstream. We investigated the velocity distribution of the wake emitted from the upstream object with changing its diameter. Also the fluctuating lift coefficient and Karman-vortex emission frequency are investigated with changing position of downstream cylinder. They are concluded as followings: i) the flow velocity in the wake is smaller than main stream, ii) the lock-in phenomenon is occurred when the upstream object"s diameter is bigger than downstream cylinder"s one, iii) in order to be maximum fluctuating lift force of the downstream cylinder in the wake, the position of the downstream cylinder must be moved with changing diameter of the upstream object together.
