From Nature to Simulation : Vortex-Dominated Flows and Bioinspired Fluid-Structure Interaction Systems
In this presentation, I will provide an overview of the ongoing research in my group at the University of Birmingham on the computational modelling of biomimetic engineering systems. These systems leverage advanced numerical methods to simulate and analyze vortex-dominated fluid flows inspired by biological systems. This interdisciplinary approach integrates principles from biology, engineering, and computational sciences to design innovative solutions that mimic the efficient mechanisms found in nature. A critical aspect of this modelling is Fluid- Structure Interaction (FSI), which examines the interplay between fluid dynamics and structural mechanics. FSI modelling techniques, such as partitioned and monolithic methods, enable the accurate simulation of complex scenarios where fluid flow influences the deformation of structures and vice versa. These techniques facilitate a detailed study of how biomimetic structures, such as flexible fins or wings, respond to fluid forces, supporting the development of cutting-edge technologies that offer sustainable and efficient alternatives to traditional engineering designs.
This talk will highlight how leveraging open-source CFD tools and high-performance computing resources allows us to capture the intricate interplay between flexible, bioinspired structures and unsteady flow fields. I will focus on various vortex-dominated flow problems, including morphing wings, free-falling seeds, and water strider propulsion phenomena, crucial to understand for applications such as bioinspired robotics and wave energy conversion using flexible membranes.
