What is POD Analysis of Tandem Square Cylinders about?
This study investigates the wake of two tandem square cylinders using Proper Orthogonal Decomposition (POD) analyses of PIV and hotwire data, focusing on the flow regimes influenced by the cylinder spacing ratio and Reynolds number. A novel POD technique, PODHW, is introduced, revealing distinct flow states of reattachment and co-shedding that were previously unobserved. The findings highlight the importance of coherent structures in contributing to fluctuating velocity energy across different flow regimes.
