Étude expérimentale de l’écoulement et de l’interaction entre deux rotors contrarotatifs subsoniques Article dans une revue avec comité de lecture;
BAKIR, Farid; RAVELET, Florent (EDP Sciences, 2014)
Recently, the need for smaller axial‐flow fans with high specific speeds leads to the design of counter‐rotating axial fans. The design of this type of machines, which have promising aerodynamic performances, suffers from ... -
Article dans une revue avec comité de lecture(American Society of Mechanical Engineers, 2013)This work provides a three-dimensional energy optimization analysis, looking for perturbations inducing the largest energy growth at a finite time in a boundary-layer flow in the presence of roughness elements. The immersed ...

The present work aims at experimentally investigating the effects of some parameters on the performances of a counter-rotating stage, and on the instationary flow between the rotors. Three counter-rotating fans, which have ...

In centrifugal and axial pumps, the flow is characterized by a turbulent and complex behavior and also by physical mechanisms such as cavitation and pressure fluctuations that are mainly due to the strong interactions ...

The unsteady character of the sheet cavity dynamics on the suction side of hydrofoils, on convergent–divergent nozzles or on blades in turbines and propellers is responsible for many issues like erosion, noise and vibrations. ...

L’étude a pour objet l’aide au développement d’une méthode de pré-dimensionnement des ventilateurs axiaux opérant en champs contraints. L’influence d’un obstacle situé à l’aval d’un ventilateur est étudiée expérimentalement ...
