Flow structure interaction between a rotating disk with bluff bodies and surrounding flow has been evaluated by using a tomographic PIV. To examine dynamics of the disk and the fluid flow simultaneously, fluorescence tracer particles and long pass filters were used. Particles and marked surface patterns were separated by an image processing. Geometries of the bluff bodies and the disk were then obtained by analyzing marked patterns. Subsequently, a particle volume was reconstructed by using of MLOS-SMART. Particle displacements were then calculated by applying the PIV algorithm to the reconstructed particle volume. Dynamics of the disk and the fluid flow were discussed with variety of bluff body shapes.
