Scientific report
The EUROMECH 654 Colloquium on "Bio-inspired Fluid Structure Interaction" was held from July 9-11, 2025, in Vienna, Austria, bringing together leading researchers from around the world to advance our understanding of how biological systems interact with fluid flows and inspire engineering solutions. The colloquium featured 38 presentations across 10 sessions, with participants from Europe, North and South America, Asia, and Australia. In addition to the regular talks two open discussion where held, discussing topics such as the benchmark of fluid-structure interaction solvers and data availability and dissemination.
The colloquium addressed a diverse range of research topics, demonstrating the interdisciplinary nature of bio-inspired fluid-structure interaction research. The presentations were organized into several key thematic areas:
Bio-inspired Engineering Applications dominated the program with 11 presentations, reflecting the field's strong focus on translating biological insights into practical engineering solutions. These studies explored applications ranging from Martian exploration aircraft to underwater robots, emphasizing the versatility of bio-inspired approaches.
Insect Flight and Wing Mechanics represented the second-largest theme with 9 presentations, covering topics from dragonfly wing resonance mechanisms to damaged wing aerodynamics. Notable contributions included the work on frequency matching in Odonata flight, which revealed a nonlinear resonance mechanism enabling energy-saving through dynamic wing softening.
Aquatic Locomotion featured 5 presentations examining various swimming mechanisms, from jellyfish propulsion to dolphin-inspired drag reduction. The research spanned from fundamental studies of shape-Reynolds number correlations in jellyfish to practical applications in underwater vehicle design.
Flexible Structures comprised 5 presentations focusing on the role of structural flexibility in fluid-structure interactions. These studies investigated how passive and active flexibility can be optimized for enhanced performance in both biological and engineered systems.
Turbulence and Flow Control included 4 presentations addressing the challenging interaction between bio-inspired systems and turbulent flows. Key findings included the discovery that turbulence can actually enhance bird tail aerodynamics and the development of dolphin-inspired skin microvibrations for significant drag reduction.
Energy Harvesting applications were represented by 2 presentations, exploring vortex-induced vibration harvesting and hydroelastic energy conversion.
Methodological Advances
The colloquium showcased significant advances in both experimental and computational methodologies. A balanced approach was evident, with studies employing experimental techniques, computational methods, and increasingly, combined experimental-computational approaches that leverage the strengths of both methodologies.
Computational Innovations were particularly prominent, featuring cutting-edge developments such as:
- GPU-accelerated fluid-structure interaction schemes
- Machine learning approaches using Fourier neural operators for design optimization
- Multi-fidelity Bayesian optimization processes
Experimental Techniques demonstrated sophistication, including:
- High-speed 3D wing deformation monitoring with simultaneous force measurement
- Advanced flow visualization using PIV, DIC, and event-based cameras
- Automated robotic experimentation for self-exploring scientific discovery
- Fringe projection profilometry for full-field deformation measurements
The integration of artificial intelligence and machine learning into bio-inspired FSI research emerged as a significant trend, with applications ranging from design optimization to flow control strategies.
Future Directions and Challenges
The colloquium identified several emerging research directions:
Multi-scale Integration: Increasing focus on connecting molecular-level biological mechanisms with macroscopic fluid dynamics performance.
Artificial Intelligence: Growing integration of machine learning and AI for both understanding biological systems and optimizing bio-inspired designs.
Extreme Environments: Expansion into challenging conditions such as Martian atmospheres, deep-sea environments, and highly turbulent flows.
Sustainable Technologies: Emphasis on bio-inspired solutions for environmental challenges, including energy harvesting and pollution remediation.
