3-D magnetic field effects during metal electrodeposition In cuboid cells

In electrochemical reactions, Lorentz forces due to external homogeneous magnetic fields may lead to increased mass transfer as additional convection is caused (MHD effect). A careful analysis shows that often a three-dimensional modeling of this effect is necessary. We will present numerical simulations of copper electrolysis in cuboid cells under the influence of homogeneous magnetic fields of different directions in the limiting current regime. The found complex interplay of natural and magnetically driven convection is compared with recent experimental results.
