Transition to chaos in the flow-induced vibration of a pitching–plunging airfoil at low Reynolds numbers: Ruelle–Takens–Newhouse scenario
TL;DR: In this article, the transition from periodic to chaotic dynamics in the fluid-elastic response of a 2-d flexible pitch-plunge flapping airfoil with chord-wise rigidity is analyzed.

An alternative simulation approach for the ONERA aerodynamic model and its application in the nonlinear aeroelastic analysis of slender wings with pylon-store system
TL;DR: In this paper, an alternative simulation approach is proposed to simplify the calculations for the ONERA model, in which the circulatory part of the OnERA model is solved analytically by using Duhamel integral method, and the corresponding aerodynamic loads can be directly expressed in the modal space of the wing motion through only introducing two additional variables.

Numerical investigation of the wake transition and aerodynamic efficiency of the two-dimensional propulsive wing
TL;DR: In this paper , the authors explored the optimal working range and wake characteristics of the propulsive wing, the wake transition and aerodynamic efficiency of the Propulsive Wing in cruise, and showed that the wake structure will change greatly at high angles of attack and lead to changes in the aerodynamic performance.

Transitional Flow Dynamics Past a Passively Flapping Airfoil in Gusty Flow
TL;DR: In this paper, the fluid-structure interaction (FSI) framework is composed of an incompressible Navier-Stokes solver weakly coupled with a two degree-of-freedom (dof) nonlinear structural model.

A complex networks based approach to nonlinear aeroelasticity
M.S. Aswathy,Sunetra Sarkar +1 more
TL;DR: In this paper , the effect of low intensity additive noise on a subcritical pitch-plunge aeroelastic system through the lens of complex networks was investigated, and the results have shown that a careful consideration of the stochastic perturbations is needed in the design and operations of such systems, and that complex networks based methods are successful in providing novel perspectives on the topology of the phase-space.

Determining embedding dimension for phase-space reconstruction using a geometrical construction
TL;DR: The issue of determining an acceptable minimum embedding dimension is examined by looking at the behavior of near neighbors under changes in the embedding dimensions from d\ensuremath{\rightarrow}d+1 by examining the manner in which noise changes the determination of ${\mathit{d}}_{\math it{E}}$.

Recurrence Plots of Dynamical Systems
TL;DR: In this article, a graphical tool for measuring the time constancy of dynamical systems is presented and illustrated with typical examples, and the tool can be used to measure the time complexity of a dynamical system.
