| Abstract | In this work, we use proper-orthogonal decomposition (POD) method to decompose an ensemble of pressure field data into spatiotemporal modes that gives insights into pressure distributions in the iceinduced vibration experiments. In the analysis, we use the Test-4300 within the Deciphering Ice-Induced Vibrations (DIIV) test campaign illustrating intermittent crushing with the ice speeds of 20 and 30 mm/s. Using an error threshold criterion, we show that first three empirical modes (hereinafter called pressure modes) represent most of the dynamics within the dataset. Although, this method successfully identifies the pressure modes in frequency lock-in and at low ice speeds in intermittent crushing, we only concentrate on low ice speeds in this paper for clarity. |
