Article dans une revue avec comité de lecture(American Society of Mechanical Engineers, 2018)This paper describes a fluid-structure interaction (FSI) model for the study of flexible cloth-like structures or the so-called rags in flows through centrifugal pumps. The structural model and its coupling to the flow ...

Article dans une revue avec comité de lecture(Elsevier, 2019)An increase in the efficiency of Small Wind Turbines (SWTs) by aerodynamic optimisation of the blade geometry is limited (low Reynolds number influence). Solutions such as the Diffuser-Augmented Wind Turbine (DAWT) and the ...

This work describes the application of a multiobjective cuckoo search method for turbomachinery design optimization of an axial pump. Maximization of the total efficiency and minimization of the required net positive suction ... -
Article dans une revue avec comité de lectureCINNELLA, Paola; (Elsevier, 2016)
Restrictions on the maximum allowable time step of explicit time integration methods for direct and large eddy simulations of compressible turbulent flows at high Reynolds numbers can be very severe, because of the extremely ...

Article dans une revue avec comité de lecture; ;ROBINET, Jean-Christophe (Elsevier, 2015)
Structural approaches based on modal decomposition of the flow dynamics have gained acceptance for a wide variety of turbulent shear flows. In this context, a singular value decomposition associated with a governing operator, ...

A new 3rd-order Vorticity Confinement scheme is presented as an extension of the original VC2 scheme developed by Steinhofffor the resolution of the fluid dynamic equations. The theoretical developments are explained, and ...

Chapitre d'ouvrage scientifique;GLOERFELT, Xavier (Springer, 2018)
In large-eddy simulations (LES), only the dynamics of large scales is computed and the effect of smaller scales is modelled. Scale separation is however difficult to establish since the low-pass filtering arises from a ...
