This article concerns "non conventional" uses of the electrochemical method applied to the study of two-phase flows.
One deals with the analysis of transport phenomena at liquid-liquid interface in a set-up where the active electrode is made of Gallium, which is a metal changing from solid to liquid state almost at room temperature (29,8 °C). With the same hydrodynamic conditions an appreciable reduction of transfer is observed when passing through the melting point to the liquid state.
The other application uses a three-segmented probe which is convenient for 3-D analysis of flow. The stability of solid-liquid flow (i.e. fiber suspension) is studied in a Taylor-Couette device. The influence of the fibers on the secondary flow is pointed out.
