Flexible slender structures are ubiquitous in biological systems and engineering
applications. Fluid-structure interaction (FSI) plays a key role in the dynamics of such …

Locomotion techniques employed by different biological animals are extremely diverse and
fascinating from an engineering point of view. The explorations of planets such as Mars …

A generic kinematic model is presented for a unified hydrodynamics study covering the
various types of motion found in real as well as hypothetical fish-like undulation. Undulating …

The objective of the current study is to leverage hereditary flexibility to enhance an airfoil's
aerodynamic performance. The aim is to understand the effect of drag reduction by imparting …

Abstract Effects of chord-wise flexibility as an instrument to control chaotic transitions in the
wake of a flexible flap** foil have been studied here using an immersed boundary method …

Unsteady flow characteristics and propulsive performance during self-propulsion of various
types of fishes-like undulating 2D NACA0012 hydrofoil are studied using a unified kinematic …

The effect of a chordwise flexible aft-tail of a rigid heaving aerofoil on the dynamical
transitions of the trailing-wake is studied here. The two-way coupled fluid–solid dynamics is …

In the present experimental study, we investigate thrust production from a pitching flexible
foil in a uniform flow. The flexible foils studied comprise a rigid foil in the front (chord length) …

In recent years, fish like whales, Tuna, dolphins, rays, etc., have been mimicked to design an
AUV because of their superior propulsion and maneuvering performance with stealth …

The hydrodynamic performance of a self-propelled carangiform swimmer with a flexible
caudal fin in the absence of a free stream is numerically investigated, where the fin's …
