Characterization of grazing bifurcation in airfoils with control surface freeplay nonlinearity
Vasconcellos, Rui M. G.
; ; ; (Eurodyn 2014: Ix International Conference On Structural Dynamics, 2014) [Trabalho apresentado em evento]
A variety of nonlinear features is obtained from aeroelastic systems with discontinuous nonlinearity motivates investigations that may support future applications in controls design, flutter prediction problems, and energy ... -
Influence of structural nonlinearities in stall-induced aeroelastic response of pitching airfoils
; Vasconcellos, Rui M. G.; (Eurodyn 2014: Ix International Conference On Structural Dynamics, 2014) [Trabalho apresentado em evento]
Stall-induced vibrations are a relevant aeroelastic problem for very flexible aero-structures. Helicopter blades, wind turbines, or other rotating components are severely inflicted to vibrate in stall condition during each ... -
Compressible modes in a square lid-driven cavity
; Gennaro, Elmer Mateus; ; (Aerospace Science And Technology, 2015) [Artigo]
This paper studies the effect of compressibility on the linear stability of a two-dimensional lid-driven cavity flow in the subsonic regime. The base flow is generated by high fidelity direct numerical simulation and a ... -
A study of the errors of the averaged models in the restricted three-body problem in a short time scale
Domingos, Rita de Cássia; ; (Computational and Applied Mathematics, 2015) [Artigo]
The objective of the present research is to study the accuracy of the double- and single-averaged models that are usually considered to predict the motion of spacecrafts or celestial bodies that have their motion perturbed ...
