Fish schooling is not merely a social behavior. Schooling improves the efficiency of movement within the fluid environment. Inspired by the hydrodynamics of schooling, a group of aquatic animals was modeled as a collection of individuals arranged in a combination of tandem and side-by-side formations. The downstream bodies were strongly influenced by the vortices shed from an upstream body. To investigate the interactions between flexible bodies and vortices, the present study examined flexible filaments in a viscous flow using numerical simulations with an improved version of the immersed boundary method. Three different filament formations were modeled to cover the basic structures involved in fish schooling, including triangle, diamond, and conical formations were examined in detail under various conditions as a model of fish schooling. The drag variations were influenced by the interactions between vortices shed from the upstream flexible filaments and those surrounding the downstream filaments. The interactions of the flexible filaments were investigated as a function of the gap distance between the filaments and the bending coefficients. The maximum drag reduction and the trailing fish position were calculated for different sets of conditions.
