Learning from nature: new body-involved performance enhancement mechanism in bio-inspired locomotion
Abstract
In this talk, a combined experimental and computational approach will be introduced for studying unsteady flow physics of freely flying and swimming animals. High-speed photogrammetry system and an accurate 3D data reconstruction technique are used together to measure the kinematics of animal body and appendages with extraordinary details. A Cartesian-grid-based immersed boundary solver is then used to simulate corresponding unsteady flows in all their complexity. Analysis of vortex dynamics due to body-appendage interactions and associated aero/hydro-performance of insect flight and fish swimming will be discussed. The discovery of the new body-involved performance enhancement will bring new insights on the design of highly efficient bio-inspired robotic systems.
