Colloquium: Aniruddha Deepak Paranjape (FPT)

Energy harvesters have been a new avenue to generate electrical energy locally for remote applications, but their flow mechanisms under different conditions have not been fully understood. This work aims to bridge this gap by characterizing the mechanisms and wake dynamics of a cylinder with a flexible splitter plate. Measurements are made at different flow speeds to characterize the behavior of the wake, and Helium Filled Soap Bubbles (HFSB) are used in flow diagnostic tools such as Lagrangian Particle Tracking (LPT) experiments. Shake-The-Box (STB) is a novel LPT tracking algorithm that uses time-resolved experimental data to predict future tracer particle locations. The raw experimental data was processed to perform statistical analysis, proper orthogonal decomposition, and spectral analysis to provide insights to meet the thesis objective.
