Unsteady inviscid flow models of wings and airfoils have been developed to study the
aerodynamics of natural and man-made flyers. Vortex methods have been extensively …

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 …

As a novel aerial vehicle, flapping-wing rotorcrafts (FWRs) leverage both aerodynamic
advantages of flapping and rotary wings, which can enhance the lift by using the passive …

Outstanding aerial capabilities that insects present in nature inspire researchers to
undertake a challenge to develop a flapping aerial vehicle with performances unmatched by …

Bathymetry is an important factor affecting wave propagation in coastal environments but is
often challenging to measure in practice. We propose a method for inferring coastal …

In recent years, there has been considerable interest in developing novel underwater
vehicles that use propulsion systems inspired by biology [1, 2]. Such vehicles have the …

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 …

This paper constructs an optimization framework based on the data-informed self-adaptive
quasi-steady model. The framework aims at achieving a specific aerodynamic force …

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 …
