Aeroelasticità computazionale con modelli CFD


Abstract


Aeroelastic analysis in transonic regime requires the adoption of accurate aerodynamic models, such as Euler or Navier-Stokes equations. This article introduces an aeroelastic procedure for fluid-structure (FSI) problems modelling, based on the integration of different commercial software. Far more computational resources than those used in the classic approach are required to solve the dynamic equations of the computational fluid dynamics. Therefore, particular attention is paid in order to define a strategy making the whole process efficient and well-suited for the realistic industrial environment problems. Current hardware resources, combined with the availability of specific software for structural and fluid dynamics analysis, such as MSC-NASTRAN and FLUENT, make the time mature for extending Computational
Aeroelasticity (CA) beyond the academic research environment, without using a specifically developed code.
