A collaborative and interdisciplinary strategy spanning hydrodynamics, sophisticated
materials, elasticity, and microelectromechanical systems technologies is required for the …

Many natural flyers and swimmers routinely flex their lifting or propulsive surfaces to control
the leading-edge vortex (LEV) that forms on the suction side during maneuvering at a high …

The study of flapping-wing aerodynamics faces a large control space with different wing
kinematics and deformation. The adjoint-based approach, by solving an inverse problem to …

It is important to understand the impact of wing-morphing on aerodynamic performance in
the study of flapping-wing flight of birds and insects. We use a flapping plate hinged with a …

An adjoint-based optimization is applied to study the thrust performance of a pitching–rolling
ellipsoidal plate in a uniform stream at Reynolds number 100. To achieve the highest thrust …

We have developed a strong-coupling approach based on a uniformly-applied Eulerian
description for both fluid and solid and provided a simple monolithic formulation to compute …

IT IS undoubtedly important to understand the aerodynamics of flexible wings of insects and
birds to improve micro air vehicle (MAV) design. The flexibility mechanism and its effects on …

A parametric study on the propulsive performance of auto-pitch wing-in-ground effect
oscillating foil propulsors (APWIGs) was conducted using an unsteady Reynolds Averaged …

OST fish and insects flap their flexible propuslors (fins/wings) to propel themselves. Their
high propulsive performance, in terms of force production and efficiency, have long been of …

Traditional proper orthogonal decomposition (POD)-Galerkin projection for reduced-order
models (ROMs) of fluid flows is based on a fixed domain. The current method removes this …
