Fluid-induced snap-through instability of spherical shells
Pier Giuseppe Ledda, Hemanshul Garg, Vitus Østergaard-Clausen +3
We study the snapping instability of a spherical elastic shell induced by a viscous flow, the umbrella flipping problem when life is at low Reynolds numbers. We combine precision d…

Computational Modeling and Analysis of Flow-induced Vibration of an Elastic Splitter Plate Using a Sharp-interface Immersed Boundary Method
Anup Kundu, Atul K. Soti, Hemanshul Garg +2
We present the development and benchmarking of an in-house fluid-structure interaction (FSI) solver. An implicit partitioned approach is utilized to couple a sharp-interface immers…
