Model Based Analysis of Forced and Natural Convection Effects in an Electrochemical Cell

Exploring the Impact of Concentration and Temperature Variations on Transient Natural Convection in Metal Electrodeposition: A Finite Volume Method Analysis

“…High metal concentration without supporting electrolyte.-The proposed algorithm, using the physicochemical properties stated in Table III, is compared in Figs. 3-5 with the benchmark cases conducted by Kawai et al, 10,43 their simulations, and also with the numerical results of Sakr et al, 44 and Brunner et al 15 Figure 3 illustrates a good agreement between the present calculated velocity profile and the experimental results obtained by Kawai et al 10 at the mid-height of the electrode (z = 5 mm) for the cell arrangement (a) sketched in Fig. 2.…”

“…34 to 41 is general and it allows to contemplate any kind of electrical control (fixed cell potential difference, galvanostatic or potentiostatic mode) in contrast to the boundary conditions proposed by other authors. 10,12,15,43,44 Types of electrical control.-In the case of a fixed cell potential difference, U, the electrodes have a predetermined potential value with the solid phase of the cathode at φ s = 0 and that of the anode being imposed as φ s = U. In potentiostatic control, the desired reference potential is set at a specific position on the working electrode and the actual value is updated after each iteration.…”

“…Additionally, a considerable number of experimental and numerical previous studies have been conducted to tackle the complex problem of metal deposition under natural convection in electrorefining, electrowinning, and electroplating. Several works 5,[9][10][11][12][13][14][15][16][17] have mainly focused on the modeling of these systems and summarized the state of the art of the subject. The developed models contributed significantly to the prediction of the experimental results and to the understanding of the problem.…”
