Abstract
Three-dimensional behavior of the low Reynolds number wake of a circular cylinder in a cross flow has been examined by 3-D PIV experiment in a circulating water channel. The wake is observed in a measurement plane fixed normal or parallel to the cylinder axis and distribution of velocity in three Cartesian components and contours of vorticity are obtained on this plane. For time-series data processing of PIV velocity fields, the sampling rate of PIV image pairs is determined with 10 % difference from the predominant wake frequency measured with Laser Doppler velocimetry. The main objective of the study is to investigate the 3-D characteristic behaviors of vortex wakes in the lower range of Reynolds numbers with laminar flow separation.
