1Department of Biological and Environmental Engineering, Cornell University, Ithaca, NY, USA.
Animals leaping from water or diving into it utilize fluid mechanics principles similar to engineering challenges. This review connects biological water-air interface dynamics to engineering solutions for bio-inspired technology.
Area of Science:
- Fluid Mechanics
- Biomechanics
- Bio-inspired Engineering
Background:
- Animals interact dynamically with the water-air interface for hunting and locomotion.
- These interactions involve complex fluid dynamics relevant to both biological systems and engineering.
Purpose of the Study:
- To review the physics of water entry and exit in biological systems.
- To connect biological strategies with engineering principles for fluid mechanics.
- To explore potential innovations in bio-inspired technology.
Main Methods:
- Analysis of biological locomotion and hunting strategies at the water-air interface.
- Application of fluid mechanics principles originally developed for engineering.
- Identification of common governing forces in biological and engineering systems.
Main Results:
- Biological systems exhibit sophisticated strategies for navigating the water-air interface.
- Fluid mechanics principles governing water entry and exit are conserved across biological and engineering contexts.
- Shared physical principles can inform the design of bio-inspired technologies.
Conclusions:
- Understanding the physics of animal interactions with the water-air interface offers insights into fluid dynamics.
- This interdisciplinary approach can drive innovation in bio-inspired engineering and robotics.
- Further research can bridge the gap between biological adaptations and technological applications.
