Convective Movements in an Electrolyser

Modeling electrolysers is a challenge because of the strong coupling between electrical, thermal and CFD equations. Indeed the electrical conductivity of the electrolyte varies with the temperature, which in turn depends on the heat dissipated by the Joule effect and anode over-voltage.In the present study, the fluid velocity values are computed near the electrodes using a diphasic level set model, but the full calculations are performed using a monophasic model. Our goal is to evaluate the relationship between the average temperature of the cell and the average current for a given cooling surface.
