Transport De Matiere Vers Une Electrode Vibrant Longitudinalement Dans Son Axe

The object of our study will be devoted to the study of the transport of matter towards a smooth annular electrode of width L, inserted in an insulating cylinder vibrating longitudinally in the direction of its axis. The movement of the electrode is generated by an exciter (mini vibrator type 4810 Bruel and Kajer), the frequency range is 0-500Hz, the instantaneous position of the vibrating electrode is measured using an inductive sensor displacement (fc = 500Hz to 3bB). During this study, we have highlighted an essential parameter which is the ratio of the amplitude of vibration A on the dimension of the electrode L. - if this ratio A / L 1).
