Characterization of nonlinear behavior of an airfoil under stall-induced pitching oscillations
(2016-06-23)
This work presents an investigation on the embedded dynamics of experimental aeroelastic signals of an airfoil under the influence of stall-induced oscillations. Helicopter blades or wind turbines are severely imposed to ...
Phenomena and characterization of grazing-sliding bifurcations in aeroelastic systems with discontinuous impact effects
(2015-12-08)
Impacts are present in real aircraft movable surfaces, such as ailerons, flaps, rudder, elevators, trim tabs among other secondary control surfaces leading to complex, dangerous, and abrupt transitions. In this research ...

Avaliação teórica de um mecanismo passivo de controle de arrasto abordando o ruído aerodinâmico aplicado ao corpo de Ahmed com traseira quadrada
(Universidade Federal de Minas GeraisBrasilENG - DEPARTAMENTO DE ENGENHARIA MECÂNICAPrograma de Pós-Graduação em Engenharia MecanicaUFMG, 2019-08-01)
A passive drag control device can increase the energy efficiency of automobiles. But, the
change in the vehicle design especially in its afterbody shape can alter the noise source related
to the turbulent flow over it. ...
Reviewing the art of modeling 3D aeroelastic behavior of cable-stayed bridges
(2015-06-21)
The development of an optimized structural design and the calculation of dynamic internal forces in the complete structure of a cable-stayed bridge under wind action is properly carried out with a theoretical-computational ...
Modeling the Pathophysiology of Phonotraumatic Vocal Hyperfunction With a Triangular Glottal Model of the Vocal Folds
(2017)
Purpose: Our goal was to test prevailing assumptions about the underlying biomechanical and aeroacoustic mechanisms associated with phonotraumatic lesions of the vocal folds using a numerical lumped-element model of voice ...
