Influence of Reynolds number and forcing type in a turbulent von Kármán flow
Brice Saint-Michel, Bérengère Dubrulle, Louis Marié +2
We present a detailed study of of a global bifurcation occuring in a turbulent von Kármán swirling flow. In this system, the statistically steady states progressively display hyste…
Forcing-dependent stability of steady states in a turbulent swirling flow
Brice Saint-Michel, Bérengère Dubrulle, Florent Ravelet +1
We study the influence of the forcing on the steady turbulent states of a von Kármán swirling flow, at constant impeller speed, or at constant torque. We find that the different fo…
Study of the cavitating instability on a grooved Venturi profile
Amélie Danlos, Jean-Elie Mehal, Florent Ravelet +2
Cavitation is a limiting phenomenon in many domains of fluid mechanics. Instabilities of a partial cavity developed on an hydrofoil, a converging-diverging step or in an inter-blad…
Design and Experimental Validation of a Ducted Counter-rotating Axial-flow Fans System
Hussain Nouri, Florent Ravelet, Farid Bakir +2
An experimental study on the design of counter-rotating axial-flow fans was carried out. The fans were designed using an inverse method. In particular, the system is designed to ha…
Imaging method for interface rheological characterization
Nicolas Abi Chebel, Olivier Masbernat, Frédéric Risso +4
The present work investigates free damped oscillations of an oil drop in water after its release from a capillary tube. Both pure heptane drops and diluted crude oil drops are cons…
Supercritical transition to turbulence in an inertially-driven von Karman closed flow
Florent Ravelet, Arnaud Chiffaudel, Francois Daviaud
We study the transition from laminar flow to fully developed turbulence for an inertially-driven von Karman flow between two counter-rotating large impellers fitted with curved bla…
