Abstract
Flowfield over and behind a circular cylinder in axial air stream was examined experimentally. To avoid disturbances from the model support, the JAXA 60cm magnetic suspension and balance system was utilized. The Particle Image Velocimetry (PIV) incorporated for velocity field measurement without interference from the model support was utilized in conjunction with the magnetically suspended model. Two PIV settings were applied in this measurement. In one setting, the laser light sheet was located perpendicular to the free stream. In another setting, the laser light sheet was located parallel to the free stream. The diameter of the model was fixed at 110mm and two length were chosen to provide L/D=1.31 and 1.68. Mean velocity and turbulence intensity distributions measured using the PIV were symmetric with respect to the center of the model. Unsteady large-scale longitudinal vortical structures were observed in the entire wake.
