Abstract
The wake dynamics behind a circular cylinder (diameter d) is investigated using a water tank
at Re=1.12x10(4乗). A Iong splitter plate with a chord length of 6d is inserted in the wake as an
interference element. Attention is made to a discontinuity of the wake dynamics, when the plate
is traversed upstream horizontally at several levels. As the plate is shifted upstream, the base
suction coefficient increases gradually, until it falls critically. Details of the vortex formation
process and its correspondence to the change in base pressure were addressed by PIV (particle
image velocimetry) .
