Journal ArticleDOI
Discrete-vortex method with novel shedding criterion for unsteady aerofoil flows with intermittent leading-edge vortex shedding
TL;DR: In this article, a discrete-time, arbitrary-motion, unsteady thin aerofoil theory with discrete-vortex shedding from the leading edge governed by the instantaneous leading-edge suction parameter (LESP) was proposed.
Journal ArticleDOI
Airfoil longitudinal gust response in separated vs. attached flows
TL;DR: In this article, a quasi-steady, linear dependence on the history of input disturbances, provided that small-amplitude bounds are observed, is explored for the problem of periodic sinusoidal streamwise gusts, by comparing experiments on nominally 2D airfoils.
Proceedings ArticleDOI
Résumé of the AIAA FDTC Low Reynolds Number Discussion Group's Canonical Cases
TL;DR: The AIAA Fluid Dynamics Technical Committee's Low Reynolds Number Discussion Group has introduced several canonical pitch motions, with objectives of (1) experimental-numerical comparison, (2) assessment of closed-form models for aerodynamic force coefficient time history, and (3) exploration of the vast and rather amorphous parameter space of the possible kinematics as discussed by the authors.
Journal ArticleDOI
Unsteady aerodynamic characteristics of a translating rigid wing at low Reynolds number
TL;DR: In this article, the force and moment histories during an extended surge motion over several chord-lengths of travel were investigated under several different velocity profiles and incidence angles, and it was determined that the formation and subsequent shedding of a leading edge vortex correspond to oscillations in force coefficients for wings at high angle of attack.
