TL;DR: In this paper, free convection and stratification of the electrolyte in a lead-acid cell with porous electrodes and during recharge were studied theoretically and experimentally, and the results from the experiments were compared with numerical results obtained from the mathematical model.

TL;DR: In this paper, the concentration and the velocity fields in a small copper refining cell with vertical electrodes were studied theoretically and experimentally, and the agreement between experimental results and theoretical predictions was found to be very good.

TL;DR: In this paper, the effect of the separator was shown to be dual: it narrows the space between the electrodes, thereby lowering the electrolyte velocity, and act as a barrier which hinders sulphuric acid to freely diffuse out and into the electrode.

TL;DR: In this paper, the concentration and velocity fields in a small copper refining cell with plane vertical electrodes were studied experimentally, where the electrolyte was an aqueous solution of 0.3 M CuSO 4 with 1.0 M H 2 SO 4 as a supporting electrolyte.
