Visualization and modal decomposition of vortex street behind circular cylinder
Original language description
Time resolved particle image velocimetry measurement of vortex street behind circular cylinder was carried out. Vortex street was measured for Reynolds numbers up to few thousands. Obtained results were processed by visualizations of moving particles andby standard evaluation of vector fields from the set of images. Modal decomposition of measured flow field was done using propper orthogonal decomposition where the structure of energetically most important modes was identified for several Reynolds numbers. The values of Strouhal number was analyzed from temporal evolution of dominant modes obtained using proper orthogonal decomposition.
