Abstract: The flow around a two-dimensional cylinder generates coherent structure and turbulence, making it a subject of extensive studies due to its relevance in various engineering applications. However, in practical engineering scenarios, cylinders are often finite-length, with one end being wall-mounted and the other free. This results in three-dimensional flow structures, making 2D analysis inadequate. The wake near a finite-length cylinder is highly influenced by its geometry. Unlike rigid cylinders, flexible cylinders experience phenomena such as bending and vortex-induced vibration (VIV), which alter their geometry and, consequently, the flow structure around them. Therefore, this study aims to numerically investigate the flow around a wall-mounted finite-length square cylinder, focusing particularly on the effects of the flexibility of cylinders using fluid-structure interaction (FSI) simulation.
