Aquatic animals exhibit efficient swimming behaviors in various schooling formations, characterized by diverse spacing and synchronization. Among these formations, the side-by-side configuration of two simplified swimmers stands out due to its intriguing self-organizing nature. This pattern emerges from a delicate balance of interacting forces, where the spacing is influenced by factors such as the Strouhal number, reduced frequency, phase synchrony, and relative kinematics of the swimmers. Through numerical simulations, we aim to deepen our understanding of self-organization, particularly focusing on the behavior of more than two swimmers. Our primary goal is to explore the possibility of achieving stable side-by-side configurations using simplified amplitude control for a series of pitching foils.
The significance of this study extends to diverse fields, including biology and bio-inspired underwater vehicles. By exploring the underlying principles that govern self-organization in multi-swimmer systems, we hope to contribute valuable insights into the domains of biology and bio-inspired engineering, ultimately leading to the development of more efficient underwater technologies.
