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
An unsteady airfoil theory applied to pitching motions validated against experiment and computation
TL;DR: An inviscid theoretical method that is applicable to non-periodic motions and that accounts for large amplitudes and nonplanar wakes (large-angle unsteady thin airfoil theory) is developed in this article.
Journal ArticleDOI
Limit-cycle oscillations in unsteady flows dominated by intermittent leading-edge vortex shedding
TL;DR: In this article, high-frequency limit-cycle oscillations of an airfoil at low Reynolds number were studied numerically, where the aerodynamic model used in the aeroelastic framework is a potential-flow-based discrete-vortex method, augmented with intermittent leading-edge vortex shedding based on a leading edge suction parameter reaching a critical value.
Journal ArticleDOI
Leading-edge flow criticality as a governing factor in leading-edge vortex initiation in unsteady airfoil flows
TL;DR: In this article, a leading-edge suction parameter (LESP) is derived from potential flow theory as a measure of suction at the airfoil leading edge to study initiation of leading edge vortex (LEV) formation.
Journal ArticleDOI
The effect of cubic stiffness nonlinearity on the vortex-induced vibration of a circular cylinder at low Reynolds numbers
TL;DR: In this paper, the vortex-induced vibration (VIV) of a circular cylinder elastically supported by linear and cubic springs is investigated numerically at low Reynolds numbers, and the results coincide with those of the linear spring when they are presented with the equivalent reduced velocity.
