Aeroelastic phenomena in turbomachinery are one of the most challenging problems to
model using computational fluid dynamics (CFD) due to their inherent nonlinear nature, the …

The paper introduces a development and application of boundary element based meshfree
reduced order model for subsonic flutter analysis of turbomachinery blade cascade. The …

It is computation-intensive and time-consuming to conduct the direct numerical simulation of
the fluid and structure interaction of an entire blade row. This paper presents a reduced …

A multi-parameter method based on multivariate spline function approximation and
minimum state smoothing for modeling the generalized aerodynamic forces is proposed in …

La prédiction numérique de la réponse de systèmes aéroélastiques devient rapidement très
coûteuse dès qu'il s' agit d'effectuer une analyse paramétrique. Le recours à un modèle …

Power loss and flow blockage in turbomachinery such as hydrodynamic torque converter
are usually caused by jet flow, second flow and flow separation. In this paper, the velocity …

Sizing the pulse magnitude for constructing dynamically time linear reduced order models
can become a labourious process of trial and error for the aerodynamicist. Improper sizing of …

An aerodynamic Reduced-Order Model (ROM) is introduced to describe the aeroelastic
behavior of a blade cascade of a turbomachine. This is obtained coupling an aerodynamic …

Dans les centrales nucléaires et thermiques, certaines installations sont sujettes à des
couplages acousto-mécaniques pouvant nuire fortement à leur bon fonctionnement. La …
