Abstract
The concentration and the velocity fields in a small copper refining cell with plane vertical electrodes were studied experimentally. The electrolyte was an aqueous solution of 0.3 M CuSO 4 with 1.0 M H 2SO 4 as a supporting electrolyte. The electrolysis was done under galvanostatic conditions. The development in time of the concentration and velocity fields was measured for different values of the current density. The concentration field was measured by Holographic Laser Interferometry (HLI) and the velocity field by Laser Doppler Velocimetry (LDV). Experimental results were compared with numerically obtained concentration and velocity profiles based on a mathematical model developed earlier. The agreement was found to be good.
