The passive response of a semi-free flexible filament in the wake of a flapping foil is studied numerically Three distinct flapping states are observed for the filament in different vortex streets: flapping between Karman vortices, flapping outside r

Flapping-wing-based propulsion is ubiquitous in Nature, and it is free in all directions. In this work, the hydrodynamic behaviour of an unconstrained flapping foil, which can self-propel in both longitudinal and lateral directions, is numerically st

The collective hydrodynamics in fish schools and bird flocks, which includes self-organization of multiple dynamic bodies, is complex and lacks sufficient exploration. In this paper, we study the performance of multiple self-propelled foils in tandem

The propulsive performance of an oblique school of fish is numerically studied using an immersed boundary technique. The effect of the spacing and wiggling phase on the hydrodynamics of the system is investigated. The hydrodynamics of the system is d

The vortex formation and organization are the key to understand the intrinsic mechanism in flying and swimming in nature. The vortex wake of dual-flapping foils is numerically investigated using the immersed boundary method. Beside the deflection of

The hydrodynamics in fish school are studied through simulating the flow over two wiggling hydrofoils in diagonal arrangement by using the immersed boundary method, both in-phase and anti-phase wiggling motions are considered in this study, the effec

The collective locomotion of two tandem autopropelled flapping foils is greatly affected by the phase difference. Two distinct vortex interactions are observed---merging interaction and broken interaction---which respectively result in the highest ef
