Abstract

We modelled a laboratory-scale fluorine reactor which employed fully coupled, fundamental electron, heat, mass and momentum transfer (two-phase) equations to deliver a transient simulation. Hydrodynamic quasisteady-state results were produced for the current density, electric field, temperature, reactive species concentration, gas and liquid velocity profiles as well as gas fraction distribution within the reactor. Simulation results were verified by modelling and comparing models from published works on similar reactors, as the laboratory-scale reactor is still in construction phase. Comparisons were favourable.
