... of a traditional Van der Pol oscillator and a Duffing oscillator; the other degree of freedom is a mass on a spring and a damper, in this case, a cylinder. Thus, this model can be considered one of fluid–structure interaction. The cubic stiffening from the Duffing oscillator proved to improve the match...

... fluid dynamics (CFD) fan blades compressor fluid–structure interaction Shape adaptation or morphing of surfaces is a concept deriving from the observation of nature [ 1 ]. For examples, birds and insects are able to achieve a wide range of flight conditions by changing their wing shape...

... and a classic spring, mass, damper mounted cylinder variable; thus, this model is one of fluid–structure interaction. This model has been previously shown to exhibit the two main aspects of NSV. The first is the lock-in or entrainment phenomenon of the fluid shedding frequency jumping onto the natural frequency...

.... In this context, this research work proposes a methodology for the design, the optimization, and the additive manufacturing of extremely stressed turbomachinery components like turbine blade rows. The presented procedure pays particular attention to important aspects as fluid–structure interactions (forced...
