Hydro dynamical dispersion in taylor-couette cells

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 of optical measurements of the concentration. In...
