This paper reports direct numerical simulations of the flow past rigid and flexible flapping
wings under hovering flight conditions. Both passive and active deformations are …

This paper investigates the flow field around a NACA (National Advisory Committee for
Aeronautics) 0012 airfoil undergoing pure pitching motion using continuous wavelet …

In this study, geometrical parameters such as twist, section thickness, and angle of attack are
numerically investigated for their influence on lift and drag coefficients, as well as cavitation …

The role of (active) dynamic wing twist on aerodynamic performance of three-dimensional
hovering flapping flight is explored using numerical simulations. A variety of cases with …

Nowadays, wind energy plays a central role in the renewable energy production, and the
optimization of wind turbine performance is the focus of current research studies. In this …

To better understand the secret of natural flying vertebrates such as how humming-birds
twist their wings to achieve superb flight ability, we presented a numerical investigation of …

An active rotor with trailing-edge flaps (TEFs) is an effective active vibration control method
for helicopters. Blade flapping dynamic characteristics have a significant effect on the active …

To better understand the function of natural vertebrates such as hummingbirds to twist their
wings, we presented a numerical investigation on the role of dynamic twisting based on a …
