Modelling and experimental evidence of the cathode erosion - Figure 12

The effect of the convection on the electric field (a), the diffusive velocity (b) and density of particle flux (c) at a current density of 10^8 A/m^2 is demonstrated. Average values of the convective velocity of 100 and 200 m/s are used to show the effect. The field reversal occurs closer to the anode (a) in the presence of convection. The reversal of the diffusive velocity is shifted with respect to the field reversal (b). The net flux of tungstem ions to the anode is fortified by the convection (c).
