Coherent vortical structures abound in both nature and engineering flows. Studying interactions with static and deformable surfaces has direct application to energy harvesting in fluidic environments, the development of modeling tools for more complex biological interactions, and the elucidation of fundamental vortex dynamics. This vein of research explores vortex interactions with both concave hemispherical surfaces, as well as deformable plates.
