The structure of the flow field inside a torque converter was quantitatively evaluated using dynamic mode decomposition (DMD). The input time series data in the interference region of the cascade blades were measured using particle image velocimetry (PIV). The spatiotemporal flow field was decomposed by DMD into several modes. https://www.spidertattooz.com/Kiara-Sky-Gel-Polish-Pixie-Dust-0-5-oz-G554-p8987/
