説明
Proper Orthogonal Decomposition (POD) or Dynamic Mode Decomposition (DMD) is a useful analysis method to extract principal components from complex flow and to understand the flow field. In POD, it is possible to extract the components of the flow which occupy a lot of energies. In DMD, it is possible to take in dynamic information by dealing with sequence of the given time series data and to observe the component of the flow which has specific frequency. In this study, flow around circular cylinders arranged independently, in series or in parallel is measured by time resolved PIV, and POD or DMD is applied to the data. In any case of model arrangement, it is confirmed that vortex shedding is expressed by pair of POD modes or DMD modes which have vortex shedding frequency or its harmonics.
