چکیده
We present experiments and simulations of plunging maneuvers large amplitude, for velocity ratios 2, defined as the ratio between peak plunge freestream velocity. explore effect airfoil shape by considering a NACA 0012 wing flat plate. The are performed with wings aspect 4 4.86, whereas using model an infinite-aspect-ratio wing. report time evolution force coefficients flow visualizations. A good qualitative agreement is found simulations, small discrepancies in maximum minimum lift observed during somewhat larger postmaneuver phase. It that has on coefficient but drag coefficient. also perform decomposition analysis to relate vortical structures wings, providing quantitative measurement leading-edge vortex trailing-edge aerodynamic forces.

Modeling the unsteady aerodynamic forces on small-scale wings
The goal of this work is to develop low order dynamical systems models for the unsteady aerodynamic forces on small wings and to better understand the physical characteristics of unsteady laminar separation. Reduced order models for a fixed, high angle of attack flat plate are obtained through Galerkin projection of the governing Navier-Stokes equations onto POD modes. Projected models are comp...
متن کاملThe advantages of an unsteady panel method in modelling the aerodynamic forces on rigid flapping wings
This paper responds to research into the aerodynamics of flapping wings and to the problem of the lack of an adequate method which accommodates large-scale trailing vortices. A comparative review is provided of prevailing aerodynamic methods, highlighting their respective limitations as well as strengths. The main advantages of an unsteady aerodynamic panel method are then introduced and illust...
متن کاملUnsteady aerodynamic forces on small-scale wings: experiments, simulations and models
The goal of this work is to develop low order dynamical systems models for the unsteady lift and drag forces on small wings in various modes of flight, and to better understand the physical characteristics of unsteady laminar separation. Velocity field and body force data for a flat plate at static angle of attack and in sinusoidal pitch and plunge maneuvers are generated by 2D direct numerical...
متن کاملAerodynamic effects of flexibility in flapping wings.
Recent work on the aerodynamics of flapping flight reveals fundamental differences in the mechanisms of aerodynamic force generation between fixed and flapping wings. When fixed wings translate at high angles of attack, they periodically generate and shed leading and trailing edge vortices as reflected in their fluctuating aerodynamic force traces and associated flow visualization. In contrast,...
متن کاملEffects of Flexibility on the Aerodynamic Performance of Flapping Wings
Effects of chordwise, spanwise, and isotropic flexibility on the force generation and propulsive efficiency of flapping wings are elucidated. For a moving body immersed in viscous fluid, different types of forces, as a function of the Reynolds number, reduced frequency (k), and Strouhal number (St), acting on the moving body are identified based on a scaling argument. In particular, at the Reyn...
