Deflection of a Smooth Cantilever Beam Caused by Fluid Pressure Gradient: A Numerical Investigation

The central objective of this study revolved around a numerical exploration, aiming to comprehend the deflection patterns exhibited by elastic cantilever beam that is deformable in two dimensions with a smooth composition. This beam’s distinctive features included sharp rectangular corners accompanied by rounded edges. The investigation was centered on the beam’s in reaction to a flowing fluid induced by a gradient in fluid pressure. To address this research question, Utilizing the Immersed Boundary (IB) technique as a computational tool, enabling an in-depth analysis of the phenomenon. A comprehensive sensitivity analysis was carried out, encompassing variations in parameters such as beam stiffness, height, and the pressure gradient within the flowing fluid. To provide context and insights, the outcomes of these simulations were juxtaposed with predictions from linear beam theory. Importantly, the findings obtained were corroborated through sound physical justifications.
