Simulation of Multiphase Turbulent Fluid Flow Through an Electrolytic Cell
A Finite Volume Method was applied to a two-dimensional model for multiphase turbulent fluid flow inside an electrolytic cell. The model is based on solving the momentum equations for the single continuous liquid phase. In the model, solid particles and hydrogen gas bubbles are treated as inert spherical particles. Once the momentum equations are solved, trajectories of the particles can be calculated by integrating the force balance on the particle, which can be expressed in a Lagrangian reference frame. Turbulence is modeled via utilizing the standard k-ε model. The paper also discusses the computational meshes, which can be used for the simulation. It is shown that usage of the boundary layer type elements decreases the total number of computational nodes while maintaining the same accuracy in calculation. It is also shown that minute changes in the geometry of the cell, such as an increase in the thickness of the plate, results in obtaining more favorable flow patterns for taking solid particles away from the electrolytic cell.
