We present detailed experiments on transient growth of turbulent spots induced by external forcing in plane Couette-Poiseuille flow, which are studied in the framework of linear of transient growth. The experimental investigation is supplemented with

Experimental characterization of micro-jets is challenging because of the small dimensions of the micro-nozzle. In this study, we propose a new technique to visualize the instantaneous 3D structure of a pulsed gas micro-jet. Using phase-averaging of

In this paper we present an experimental and theoretical description of the dynamic of spatial patterns obtained in a video feedback loop. A video camera monitors the screen to which it is connected and can turn around its optical axis at an angle al

In this article we study the mass tracer dispersion in organized flows For this purpose we performed experiments in the flow arising from the Taylor-Couette hydrodynamic instability combined with axial flow. The tracer evolution is followed by means

Hydrodynamic stability is of fundamental importance in fluid dynamics. As a well-established subject of scientific investigation, it continues to attract great interest in the fluid mechanics community. Bifurcations and instabilities are observed in

Countercurrent chromatography (CCC) is a separation method based on the partition of solutes between two liquid phases, as they interact in a thin tube under centrifugal forces. Many different versions of CCC instruments have been developed over the

We present experimental results on the mass tracer dispersion in an organized cellular flow, with stationary and propagating cells, arising from the centrifugal Taylor-Couette (TC) hydrodynamic instability [1]. An axial flow is superimposed to the an
