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.

Physics of animal collective behavior : interactions with one another and their environment
The breathtaking aerial displays and mesmerizing formations of birds, fish shoals and the thunderous gallop of hundreds of horses exemplify captivating group behaviors in nature. Traditional measurement methods fall short in capturing these intricate behaviors arising from simple individual interactions, (…) -

Discharge Flow of a Granular Media from a Silo : Experimental investigations and continuum modeling
Silos are widely used in the industry. While empirical predictions of the flow rate, based on scaling law, exist for more than a century, recently advances have been made on the understanding of the control parameters of the flow. In particular using a continuum model together with a visco-plastic frictional (…) -

Coarse-grained models for schooling swimmers in fast flows
The beautiful displays exhibited by fish schools and bird flocks have long fascinated scientists, but the role of their complex behavior remains largely unknown. In particular, the influence of hydrodynamic interactions on schooling and flocking has been the subject of debate in the scientific literature. I will (…) -

Flowing through a world of patterns
Why is there so much structure, order and texture to life and nature, rather than a featureless expanse ? From microscopic snowflakes to dried mud and vast river networks, pattern formation gives rise to systems of extraordinary intricacy and beauty. Understanding how a system spontaneously selects its overall (…)
The audience is composed of people with rather heterogeneous backgrounds including specialists in solids, fluids, granular flows, statistical physics... so the idea is to keep your talk understandable by people not necessarily working in your field... The seminar time slot runs from 11am to noon so the best is to make the talk last around 45 minutes to leave some time for discussion.
