A geometrical configuration and its effect on the performance of an electrochemical cell under free convection
Watheq Naser Hussein1.
The effect of positioning or location of the cathode electrode with respect to the
surface margin of the electrodeposition electrolyte solution under free convection
was numerically studied. The importance of such study arises from the fact that
there is no study, according to the author's knowledge regarding the effect of
electrode positioning (depth effect) and its effect on the current distribution and
on the free convection (absence of forced convection) hence, its effect on mass
transfer, that highly appears in the industrial application. It was shown that
positioning of cathode near the surface of the solution gave bad results of deposits
distribution while moving it downward has comparable results to that when the
electrodes are in the middle of the electrolyte. Accordingly, the best configuration
was achieved when the cathode location approximately is in the middle of the
electrolyte with applied currents-as in this study of about 4.6 mA/cm2
-.
According to this study, it was found that there was no effect of free convection
on the mass transfer or on the flux of Cu+2 ions and the main contributed
mechanism is the diffusion one.
