In nature, the phenomenon of cluster movements of fish, birds, and insects is universal,
which constantly inspires people to explore its advantages. In this study, the aerodynamic …

Collective movements are common in nature, such as the swimming of fish schools and the
flight of birds in formation. The aero/hydrodynamic performance of such movements is a …

Tandem flapping-wing micro aerial vehicles, which are inspired by dragonflies, are unique
in that they have two pairs of wings, and this could increase their maneuverability during …

Direct numerical simulations have been performed to analyze how three-dimensional effects
influence the performance of wings in tandem configuration undergoing a two-dimensional …

In nature, insects with their forewings and hindwings undergoing small-gap flapping motion
experience strong aerodynamic interaction. Conventional studies mainly focus on the …

This paper reports a fundamental investigation on the aerodynamics of two-dimensional
flapping wings in tandem configuration in forward flight. Of particular interest are the effects …

The aerodynamic performance of twin NACA0012 flapping wings is investigated for different
combinations of sinusoidal plunge and pitching motions employing Reynolds Averaged …

This experimental study investigates the effect of a uniform lateral inflow on the aerodynamic
characteristics of flapping wings. Seven designated sideward ratios in the hovering …

In nature, creatures such as birds, insects, and fish have excellent flight and mobility
capabilities. The prominent flight performance of many creatures employing flapping wings …

We report direct numerical simulations of a pair of wings in horizontal tandem configuration
to analyze the effect of their aspect ratio on the flow and the aerodynamic performance of the …
